Battery performance
To keep your battery in the best
condition, leave the handset off the
base station for a few hours at a time
(after the initial 16 hour charge).
After charging your Synergy
handset for the first time,
subsequent charging time for the
battery is approximately
4-5 hours. Battery and case may
become warm during charging.
This is normal and not dangerous.
Under ideal conditions, the handset
battery should give about 12 hours
talktime or 150 hours standby on a
single charge.
Please note, however, that a new
NiMH battery does not reach its full
capacity until it has been in normal
use for several days.
Please note that while the NiMH
rechargeable battery can be
expected to give years of service
they do not last forever.
Their actual lifespan depends on
how heavily they are used but over
time, their capacity to recharge will
begin to diminish and they will
eventually need replacing.
Battery low warning.
If the handset battery symbol is
empty and flashing, and you hear
a warning beep every 10 seconds,
you will need to recharge your
handset before you can use it.

Charge the handset battery
for at least 16 hours
Before you use your Synergy 2120 for
the first time, it is important to have
the handset battery fully charged.
We recommend that you leave the
Synergy 2120 on charge for at least
16 hours.
Place the handset on the base. The red
charging light comes on. The handset
should come pre-registered to the
base station as HS1 and this is shown
in the top right corner of the display.
The battery symbol is also shown.
It flashes during charging. Once the
handset is fully charged, the display
shows a full battery symbol.
