The green LED on the cover of the Ei428 will change to red and flash slowly, this indicates that it will receive the unique serial numbers being sent by all other RadioLINK units in ‘House Code’. The number of flashes of the LED indicates the number of units in the system, The Ei428 will return to normal standby mode automatically after 15 minutes. Pressing the ‘House Code’ switch again will return it to normal standby immediately.

Practical Tips In Building a Stronger Marriage
Format: Audiobook
I purchased my first copy of “The Five Love Languages: How to Express Heartfelt Commitment to Your Mate” by Gary Chapman in 1992. After spotting him in North Carolina earlier this year, I decided to purchase the audiobook. Not only did I want to listen to Chapman read his book out loud, but I also wanted to digest his work through the lens of older, hopefully wiser, eyes.
In a recent Bible study, someone brought up the verse about flattering lips. I thought this was an excellent segue into one of Chapman’s love languages—words of affirmation. Numerous people feel extraordinarily loved when they are appreciated. The other four primary love languages the author discusses are: gifts, physical touch, quality time, and acts of service.
I especially appreciated Chapman’s chapters on applying the love languages when only one partner is interested in improving the relationship. He offers practical tips, encouragement, and step-by-step examples on how to gather your partner’s complaints, address their frustrations, and show them love, regardless of your or their love language.
One addition I would have appreciated in Chapman’s reference to “Loving the Unlovely” would have been to address a hyper-critical spouse who refuses to offer words of affirmation or positive feedback. Chapman’s technique for improving a marriage relies on the other spouse responding. Regardless, Chapman’s technique has undoubtedly helped hundreds of struggling wives and husbands feel loved and experience a successful marriage.
This classic is an excellent Bible Study resource for small groups, Bible studies, and couples.
If you enjoyed “The Five Love Languages: How to Express Heartfelt Commitment to Your Mate,” you may enjoy “For Women Only, Revised and Updated Edition: What You Need to Know About the Inner Lives of Men” by Shaunti Feldhahn and “For Men Only (Revised and Updated Edition): A Straightforward Guide to the Inner Lives of Women” by Shaunti and Jeff Feldhahn.

Materializing the Intangible Force of Love
Format: Paperback, Format: Paperback
Introduction:
In “The 5 Love Languages”, Gary Chapman displays his masterful understanding of the single factor necessary to create and maintain a healthy relationship – Love.
Through his experience as a counselor, stories from the road and journey as a student, Dr. Chapman has been able to materialize the immaterial force which permeates all marriages and relationships, providing the advice which almost no one can articulate.
Dr. Chapman has found the languages of love itself, “Words of Affirmation, Quality Time, Receiving Gifts, Acts of Service, and Physical Touch.”
What You will Gain:
After reading this book, you will find yourself rapidly improving your relationship with your spouse, children, and family. I the heard enthusiastic, supporting words, “Our relationship has been different over the past week!” after implementing the wisdom from “The 5 Love Languages.”
You will even find yourself watching drama-filled talk shows like “Dr. Phil,” being able to pinpoint each spouse’s love language and how they are not fulfilling it based on their complaints.
It is very enjoyable to wield this skill, but also extremely practical. Instead of criticizing your spouse, you can create the environment to facilitate change, and the best part is, both partners do not have to be on the same page! That’s right,” The 5 Love Languages” work without needing both partners to read, so if you didn’t marry a reader, you’re in luck!
Conclusion:
This was my first dedicated relationship book, and I’m glad it was. “The 5 Love Languages” was not only a quick read, but easy to digest and entertaining. I purchased it for the incredibly low price of $6.86 in new condition (can’t get much better than that, even at a used bookstore).
Based on all the things discussed above, I can easily endorse this book and frankly recommend it to everyone! Even if you’re not married, this book covers relationship dynamics you can apply anywhere.

Excellent advice on how to improve relationships
Format: Kindle
I've read dozens of books on the psychology of relationships, but this is one of the best and most useful I've ever seen. Gary Chapman's unique concept of "The 5 Love Languages" (Affirmations, Quality Time, Acts of Service, Gifts, and Physical Touch) describes how knowing and using the 5 love languages can improve and deepen loving relationships, while misunderstanding them can cause harm. The information in this book is well-organized, easy to read and understand, and includes lots of stories that are not only interesting, but clearly illustrate the author's point. There is also a self-assessment tool at the end, plus links to additional info online.
Dr. Chapman's basic concept is that "5 love languages" are commonly used in committed relationships to express love and affection toward one's partner. Chapman explains that loving couples can run into trouble if they don't know and understand their own dominant love language or that of their partner. A relationship can thrive if and when each person understands which specific love language is most important to themselves and also knows and honors their partner's most important way of receiving love, which is often different from their own. All 5 of the love languages are equally useful and valid; none are better or more preferred than any other. They simply reflect how an individual's unique needs, expectations, and personality are expressed by the ways they most want to receive love from their partner.
Dr. Chapman devotes a chapter to each of "The 5 Love Languages" using stories from his practice as a licensed Marriage and Family Counselor to show the need for using the correct expressions of love and how using the wrong love language can damage an otherwise good relationship. For example, if a wife's dominant love language is affirmations (including compliments, encouragement, appreciation, and gratitude) but her husband doesn't understand how important these positive words are to her, he might think it's OK to tease her about her looks, accuse her of being lazy, or criticize her cooking. When she needs kind and supportive words but hears insults and put-downs instead, she will feel unloved, no matter what else he does to show he cares. He could surprise her with flowers, hug and kiss her when he comes home, fix the leaky faucet, or offer to take the kids to the park, but still, if he does not give her the words she needs, she will feel unappreciated and unfulfilled. On the other hand, if the husband's dominant love language is spending quality time with his wife, but his wife thinks that taking good care of the house & kids and cooking him a nice meal every night is the best way to show him her love, he will feel resentful and misunderstood. What he needs most is for her to set aside time for listening and sharing with him, for making plans, and spending quality time one-on-one. If she does not understand how important quality time is to him, that will damage their relationship. Having a weekly date night is probably the most important thing this couple could do to improve their marriage.
"The 5 Love Languages" is written specifically for married couples, but the advice could easily be applied to ANY relationship, including family and friends. The author has written other books using the 5 languages concept, such as "The 5 Love Languages" for parents - how to express love to their children and teens. Some kids thrive on physical touch when young, but the kind of touch is likely to change when they become teens. Some kids rely on quality time with one or both parents, while others want more time alone but still need to hear lots of affirmations. I wish I had known about "The 5 Love Languages" when my kids were little, but now that they are grown I can still use what I've learned to improve all my relationships.
Overall, this book is the real deal, both important and useful. I highly recommend "The 5 Love Languages" to anyone wanting to learn how to improve and express love in their relationships.
