10-2. Re-registering the Handset

When you first put your handset into the base, it is registered so it can communicate with the base. There may 
be some times when you have to re-register your handset to the base:

When you want to change the handset-to-base code. 
When there is a power failure that lasts more than one hour.
If the handset's battery is completely discharged. (The handset must be recharged for 15 - 20 hours before 
re-registering to the base.)
Any time you experience difficulty connecting to the base to make or receive calls.

To re-register the handset:

Pick up the handset from the base. Press and hold 

[find hs]

 on the base.

While holding 

[find hs]

, place the handset in the base. The 

charge/in use

 LED on the base begins to 

flash, indicating the base is registering the handset. Wait for at least five seconds.
Pick up the handset from the base and press 

[TALK/flash]

. If the display shows TALK, the handset is 

registered. If not, place the handset in the base to try again. 
Press 

[END]

.

10-3. Changing the Handset-to-base Code

The handset-to-base code prevents other cordless devices from accidentally connecting to your base. If the 
battery pack is completely discharged or removed, the handset-to-base code will be lost. If this happens, a new 
code is set automatically the next time the handset is charged in the base. In the rare situation that you suspect 
another cordless telephone is using the same code, you can change the code.
To change the handset-to-base code, re-register the handset to the base following the instructions in section 
10-2 on Re-registering the Handset above. 

10-4. Traveling Out of Range

During a call, as you begin to move your handset too far from your base noise increases. If you pass the range 
limits of the base, your call will terminate within one minute.

10-5. Liquid Damage

Moisture and liquid can damage your cordless phone.

If the handset or base is exposed to moisture or liquid, but only the exterior plastic housing is affected, wipe 
off the liquid, and use as normal.
If moisture or liquid has entered the plastic housing (i.e. liquid can be heard in the phone or liquid has 
entered the handset battery compartment or vent openings on the base), follow the steps below:

Handset

Base

Remove the battery cover and leave it off for ventilation.

Disconnect the battery pack. Leave the battery cover off and the 

battery pack disconnected for at least three days.

the battery cover.

IMPORTANT: 

You must unplug the telephone line while recharging the battery pack to avoid charge interruption.

CAUTION!

DO NOT use a microwave oven to speed up the drying process. This will cause permanent damage to the 

handset, base and the microwave oven. After following these steps, if your cordless telephone does not work, 

please call our Customer Service Hotline. See back cover page for contact information.

10-7. Power Failure Operation

10-8. Battery Information

Average battery life

With average use, your handset battery provides approximately six hours of talk time and approximately 
fourteen days of standby time. You can achieve optimum battery life and performance by returning the handset 
to the cradle after each use. When your handset is left off of the cradle, the battery will gradually discharge 
even if the handset is not being used. The actual talk time duration will be reduced in proportion to the amount 
of time the handset is off the cradle.

Low battery alert

When the battery pack is very low and needs to be charged, the phone is 
programmed to eliminate functions in order to save power. If the phone is 
not in use, LOW BATTERY CHARGE HANDSET appears on the LCD, and none 
of the keys will operate. During a call, the handset beeps, and the LCD 
flashes LOW BATTERY. Complete your conversation as quickly as possible 
and return the handset to the cradle for charging.
Note: Information stored in the phone's memory will be retained for thirty minutes after the battery pack is 

removed. This includes all setup information, last number dialed, speed dial memory, and the CID list.

Battery replacement and handling

When the operating time becomes short even after a battery is recharged, please replace the battery. With 
normal usage, your battery should last about one year. To order replacement batteries, please contact Uniden’s 
Parts Department. The contact information is listed on the back cover page.
