Connecting Remote Speakers
You must connect remote speakers to the radio bodies if:
■
using a hand-held control head, or
■
using a control head with a graphical-display and you want to enhance
or replace the control head’s internal speaker.
The remote speaker will only sound audio from the radio that it is connected
to. Audio is never fed to a remote speaker from the other radio body. If a
radio is at the background and dual receive is activated, the attached remote
speaker will sound received audio from that radio at a reduced volume. If a
radio is at the foreground, the attached remote speaker will sound received
audio from that radio at normal volume, and audible indicators.
The following high-power remote speakers are recommended:
■
TMAA10-06 high-power remote speaker for >25W radios
■
TMAA10-03 high-power remote speaker for 25W radios.
If a different speaker is used, receptacles for the speaker pins of the power
connector are provided with the installation kit. The installation kit also
contains a flying lead connector that, when installed, enables the speaker to
be easily removed and re-installed as required.
The speaker is connected to pins 2 (SPK–) and 3 (SPK+) of the power
connector. See
. For more information, refer to the
installation instructions provided with the speaker, or to the relevant section
of the service manual.

Installing a Cross-band Linking Cable
The TMAA04-04 or TMAA04-06 cross-band linking cable can be used to
extend the features available with TM8260 dual radio systems. The cables
connect to both radio’s auxiliary ports so the radio system can be used as a
cross-band repeater. The TMAA04-06 cable provides additional
connections to enable, for example, GPS operation and power via ignition
sense.
For cross-band pins and signals on the auxiliary connector, see
Notice
The radio does not meet the IP54 protection standard once the
auxiliary connector rubber bungs have been removed and this cable has
been installed. Care must be taken when the radio is being operated in
an environment where there is water, dust or other
environmental hazards.
