Charging the batteries
1. Place the handset in the handset charger. The
handset turns on, and the battery charge indicator
in the display starts to flash.
2. Charge the batteries for at least 10 hours before
first use.
Registering handsets with the base
You must register the handsets with the base. You can use the handset charger, or you can use
the handset itself.
NOTE: If the handset you want to register is already registered with another base, you need to
deregister the handset from that base before you can register it with a new base. See
Deregistering a handset from a base
on page 93.
Using the handset charger
1. Press the
Reset
button on the back of the base. A five-minute registration period starts,
which allows handsets to register with the base.
NOTE: If you have multiple bases, only reset one base at a time, and wait five minutes before
resetting the next base.
2. If the handset is turned off, press the
Red Phone
key to turn it on.
3. Place the handset in the handset charger. The handset automatically registers with the base,
and the
Configure SIP Domain
message appears on the display. This message indicates that
you must configure the TS-850i as an IP extension, as described later.
A base can support up to three handsets with three concurrent calls. It can support up to
eight handsets if they aren’t all used at once. If you have more than three handsets and are
getting busy signals, add more bases to your installation in order to handle more calls.
