1.5.2 DE-REGISTRATION Whether you want to de-register both handsets or remove one handset
only, you can de-register the handsets from the base unit. However,
you must move the handset unit close to the base to receive the de-
registration command from base unit. After de-registration, the
handset unit no longer links with the base.
There are 2 ways to de-register the handset unit:
• using the base only
• using the base and the handset.
1.5.2.1 Using the Base Only
1. To de-register all handsets, turn off dip switches 1 and 2, and
turn on dip switch 3. After 5 seconds, the system de-registers
all the handsets.
2. To de-register Handset #1, turn off dip switch 3, and turn on
dip switches 1 and 2. After five seconds, the system de-regis-
ters handset #1.
3. To de-register Handset #2, turn off dip switches 2 and 3, and
turn on dip switch 1. After five seconds, the system de-regis-
ters handset #2.
4. Finally, change the dip switch on the base to normal mode (all
switches off). The LED on the base flashes normally when the
unit returns to normal mode.
1.5.2.2 Using the Base and Handset
1. The base is in the idle mode.
2. While the handset is in standby, press and hold the F1 soft key
for just over 2 seconds to enter System Programming Mode.
Then use the up or down soft key to select DE-REGISTER.
