2. Nominal base
station TX level
would be 1 Vp-p
b. Adjust the level at TP16
(2005698 controller card) for
1 Vp-p
i. REC gain adjustment
R105(2005141 controller
card front panel).
1. Ensure tone is not
clipped by viewing
waveform with an
oscilloscope.
2. TX adjustment (If one way
communication, then this step
can be skipped)
a. Simultaneously press buttons
5 & 7 on the 2005698
controller card. This will cause
the controller to transmit for
approximately 8 seconds.
b. Determine proper siren TX
level required.
i. Nominal UV TX level
would 1 Vp-p.
ii. The TX levels for all of the
siren controllers must be
the same.
1. Once one siren TX
level is adjusted, all
other sirens must
be adjusted to the
same level.
a. Measured at the
Base station.
c. Adjust the TX level (2005698
controller card front panel) for
the correct level determined
above.
d. Ensure tone is not clipped or
distorted by viewing waveform
with oscilloscope.

7.6 600-Ohm Adjustment
Procedure for External
Audio Source Input
Note: To use the 600 ohm input for
external audio, at JP6 a jumper must
be across pins 1-2. JP6 is located
internally on the main controller card.
1. Audio source adjustment for
external audio source.
a. Transmit a tone from the
external audio source.
i. Ensure tone is not
clipped or distorted by
viewing waveform with
an oscilloscope.
ii. Nominal external audio
source level would be
1 Vp-p.
iii. If required adjust the
external audio source.
2. Audio source adjustment for UV
controller.
a. Transmit a tone from the
external audio source
b. Contact closure at JP15 pins
10 and 11 (PTT: Push To
Talk) is required to activate
audio mode.
c. Adjust the level using the
external audio gain
adjustment R123
d. (R123 located internally on
the 2005698 controller card
circuit card).
i. Preferred method of
setting this level is to use
a dB meter or by ear.
1. Activate siren via
external audio
source.
