Connecting and positioning
detached antennas
In situations where the location of the receiver is
not identical to the antenna location which would
give optimal reception, there exist the two possi
ble remedies illustrated in Figs. A and B.
Note on Fig. A: A further improvement in reception
conditions can be achieved simply by inserting a
second G2A 1001 {drawn in dashes) into the
antenna jack on the receiver and connecting the
detached antenna to antenna jack B. The optimale
solution is illustrated in Fig. B. This should always
be used if the highest degree of transmission
safety is required. The at first sight "simple
2-antenna technique' is more than this, since an
electronic circuit constantly checks the antenna
voltage and switches the antenna providing the
current highest signal to the receiver.
Some notes which must always be observed
when positioning the antennas:
- Locate the antennas in the room where the
transmission is occurring.
— To avoid any interference do not locate anten¬
nas near digital controlled comoponents.
— Keep a minimum clearance of 1 m from metallic
objects, including reinforced concrete walls.
- The distance between transmission and recep¬
tion antenna should be at least 3 m.

Possible cause
Fuse defective
1. Transmitter not switched on
2. Transmitter frequency does not match the
receiver frequency.
3. Response threshold for the squelch circuit
set too high (see section concerning
'Adjusting the squelch').
1. AF output signal set too high. Input of the
down line mixer or amplifier is being over¬
driven (see the section concerning
'Adjusting the AF-output voltage').
2. Microphone at transmitter overdriven.
(See corresponding section in the user's guide
for the transmitter).
