1. BATTERY TEST
Touch battery terminals to the two BATTERY
TEST terminals, observing proper polarity.
Replace battery if reading is less than 7.0.

2. TRANSMITTER TEST
The TEST SET will provide a rapid indications of
relative signal output of the transmitter. Judgments
of the actual signal output level can be made only by
comparison with a known good transmitter. The
TEST SET also provides an indication of the
approximate transmitter frequency. Since indication
is only approximate, the TEST SET cannot be used
to guarantee frequency settings within the
tolerances of the factory adjustment. When used to
test transmitter output, TEST SET provides no
indication of the existence or adequacy of TONE
modulation, but DIGITAL modulation causes the
meter to pulsate at about 12Hz rate.
To test the transmitter for relative output signal place
the TEST SET on a non-metallic surface. Place
the transmitter against the lower edge of the TEST
SET as shown in FIGURE 1.

RECEIVERS
Plug test cable into TEST SET . Remove
antenna from receiver and open receiver
cover. Connect clip lead to coil lead L2
ground. See FIGURE 2. Push prod tip lead
into antenna socket. Proceed to 7.
Press transmitter button and carefully adjust tuning
knob on the TEST SET for a maximum meter
reading. If TEST SET needle deflects off scale
back transmitter away from TEST SET. (DO NOT
ATTEMPT TO TUNE TRANSMITTER BY USING
TEST SET ALONE AS A TUNING INDICATOR>
SEE 3.).
IN THE FOLLOWING STEPS, THE SECURITY
SWITCH ON ALL RECEIVERS SO EQUIPPED
MUST BE IN THE UNLOCKED POSITION.

4. DIGITAL CODED TRANSMITTER
ALIGNMENT AND RECEIVER TEST
Note: Digital receivers are not supplied with
an antenna rod.
Plug test cable into TEST SET . Open
receiver cover. Connect clip lead to the
jumper wire as shown in FIGURE 3 Push
prod tip lead into antenna jack. Proceed to 7.

5. TONE OR DIGITAL CODED TRANSMITTER ALIGNMENT AND RECEIVER TEST:
28 VAC H.D. MOUNT RECEIVER.
Plug cable into TEST SET. Remove antenna
from receiver and connect clip lead from TEST
SET through hole in bottom of receiver case to
the lead as shown in FIGURE 4 Push prod tip
lead into antenna socket. Proceed to 7.

6. TRINARY CODED TRANSMITTER
ALIGNMENT AND RECEIVER TEST
Plug test cable into TEST SET . Access
receiver board by opening case or removing from
wall push prod tip lead into TP jack and connect
clip lead to any negative point on board such as
left and of R4 See FIGURE 5, 6 or 7
