2.5 Outstation Final Setup
Balance the fire telephone as per DEL2073 (by operating the test button and adjust VR1)
Attend the first outstation, with a partner at the Control Panel - press the call button on the front of
the outstation and ensure that two-way communication is established. End the call at the panel by
replacing the Handset. If there is feedback the volume setting is too high, therefore, back off the
volume slightly by adjusting VR5 and retest.
Repeat this for all the remaining outstations.
