Alignment Point Location on Base Main PCB and Base RF PCB

Preset

a) Remove the solder on the pattern (refer to the illust. below).

b) Set the “TONE/PULSE” switch to PULSE.

c) Connect the AC adapter to the base unit while pressing the “PAGE” key, and keep pressing it continuously for

approximate 2 seconds.

d) Release the “PAGE” key when entering TEST mode 1 with IN USE/CHARGE LED lighting.
