Battery Installation - AT&T Trimline TR1909 User Manual

Getting started

Battery installation

Before using the telephone, you should install four good AA alkaline batteries
(not included) to provide memory backup and enable the use of some features.
The four AA batteries are required for caller ID features and the IN USE light to
work. If good batteries are not installed, the display only works when you lift
the handset.
If you unplug the telephone from the wall jack, or you lose telephone service
for over 10 minutes, and good batteries are not installed, the following
information is lost: call list, numbers stored in one- and two-touch memory,
redial list, and all settings in the feature menu. It is recommended that you
initially install new batteries and change the batteries soon after the low
battery icon appears.
1. Press on the tab to open the cover of the battery compartment.
2. Install four new AA batteries (not included) in the battery compartment
according to the label + and - engraved in the compartment.
3. Close the battery compartment cover. Make sure it clicks into place.
Step 1
NOTES:
• Do not mix old and new batteries and do not mix alkaline and standard
(carbon-zinc) batteries.
• When the batteries are installed, the screen will show 12:00 and the clock
will begin to run. It will reset to the correct time when the first caller ID
data is received.
• Always disconnect all telephone lines from the wall outlets before replacing
batteries.
• Install new batteries every six months to maintain the call log and
telephone memory.
