Connecting a Remote Speaker
If a high-power remote speaker is required, Tait recommends using the
TMAA10-03 high-power remote speaker for 25W radios. Installation
instructions (IPN 402-00010-xx) are provided with the speaker.
If a different speaker is used, it can be connected to the flying-lead connector
already installed in the power connector (
b
), or connected using the two
spare receptacles that are provided with the installation kit (
c
).
1.
Run the speaker cable to the radio, then (underneath the RF ampli-
fier) alongside the ignition sense cable to the back of the radio body.
2.
Secure the speaker cable with cable ties using the small holes in the
side of the chassis (see
Figure 3.3 on page 17
), as was done for the
ignition sense cable.
3.
Connect the remote speaker connector to the flying lead connector
(shown in
Figure 3.4
option
b
).
If connecting the speaker directly to the power connector
(
Figure 3.4
option
c
), connect the speaker to pins 2 (SPK–) and
3 (SPK+) of the radio body’s power connector (see
Table 3.1
).
