Control Head The control head is attached to the radio body. There is a choice of three
control heads:
■ two-digit-display control head
■ one-digit-display control head
■ blank control head
The control heads with a display provide an interface with the radio user
and include a socket for the connection of a microphone. (Aside from
the number of characters displayed, there are no other differences
between these two control heads.) The blank control head has no UI
(user interface) but has a single external connector called the
programming connector; this is typically used for monitoring purposes.
For calibrating and programming the radio, the control head is connected
(via the microphone or programming connector as appropriate) to the
PC on which the calibration and programming applications are installed.
Designations The designation of the radio depends on which control head is attached
to the radio body:
■ TM8115 : two-digit-display control head
■ TM8110 : one-digit-display control head
■ TM8105 : blank control head
Illustrations of the TM8115 radio are given in Figure 1.1 and illustrations
of the TM8110 and TM8105 in Figure 1.2.
Audio Accessories One or more audio accessories may be connected to the control head
and radio body. A microphone is the accessory usually required; other
accessories that are available are a handset, high-power remote speaker,
and hands-free kit. Various external devices may also be connected. The
user’s guide and accessories manual describe the audio accessories.
Installation Kits and
Desktop Power Supply
The mounting hardware for the radio is in the form of a U-cradle. It is
supplied in an installation kit and provides for the installation of the radio
in a vehicle. Alternatively, the radio might be needed for desktop use, in
which case a desktop power supply is required. Tait desktop power
supplies include the parts needed to mount the radio. The user’s guide
and accessories manual describe the installation kit.
Block Diagrams
of System
The block diagrams of Figure 1.3 to Figure 1.5 illustrate possible
configurations of the radio system. Figure 1.3 and Figure 1.4 show
example installations of the TM8110 or TM8115 radio in a vehicle and
on a desktop. Figure 1.5 shows an example of the TM8105 radio (with
blank control head) installed in a vehicle. Different audio accessories are
shown connected to the radio. The hands-free kit is connected to the
auxiliary connector, and the remote speaker to the power connector.
The accessories that may be connected to the microphone connector
include the rugged microphone, as well as a DTMF (dual-tone multi-
frequency) microphone, desktop microphone, and handset.
