Uniden D1483 base just flashes 88 - Uniden 5.8GHz Expandable Cordless Phone System with Digital Answering System

If there is an error code with an E followed by a number or "88" displays/flashes it would be an internal issue in the base unit. Uniden does offer a limited 1 year warranty (Covers Manufacture Defects ONLY, if caused by a power surge or power outage or any other type of damage that is not a Manufacture Defect this is not covered under warranty) off the proof of purchase. The proof of purchase is required for warranty service.

Press MENU/SELECT, select "Answering Setup," then select "Ans. On/Off." See the instructions beginning on page 9 of the manual: Owners Manual User Guide for Uniden D1483 Dect 6 0 Cordless Phone With...

The number usually indicates how many messages are stored! I think the memory is full so not allowing any more calls...... Delete the messages!

Range form base should be less than 100feet in most all homes don't think they are designed for long range ever

Yes, the main unit will always work,

I spoke to the manufacturer this morning because I was having the same issue ... I was told that the flashing 88 means that the base unit is has gone kaput and is no longer working. period.

customer service said that this can happen due to electrical issues and the company will send me a new base unit and handset to replace the one that no longer works.

I just got off of the phone with Uniden for the same issue with my D1680-4. The alternating "8" - "88" code is an indication that the base is dead. They will be sending me a new base (and 2 handsets). During the call I learned that if you do not have a receipt, Uniden warrants their phones for up to 15 months. The advertised 12 months, plus 3 months for the product to get from manufacturing, through distribution channel and finally sale to the consumer.

Your manual may have the E4 code, but Uniden certainly will, if you contact their support site. This symptom often indicates a power or function issue with the base unit, and so make sure the base has charging voltage, and the terminals are clean (use a qtip and alcohol). When you contact Uniden Support, have your model number ready, since different units can have the same or different error codes programmed into them.
Good luck, and hope this helps.

Try a new battery. That is usually what "88" means.
