• The power supply converts AC power into DC power for use by the radio’s
transceiver and the Audio Interface board or optional Tone Remote Control
board.
The ASTRO Spectra/Spectra Plus control head and speaker are present in all
W7 models. W9 Digital Remote Control models do not have a control head or
speaker. Refer to the appropriate ASTRO Spectra/Spectra Plus radio user’s
guide for information regarding the operation of the control head.
The accessory connectors (see Figure 2 on page 6) are used to connect
external equipment to the Consolette. Accessory Connector 3 (top) is currently
used for tape recorder audio out. Tone remote desksets or digital remote
desksets should use Accessory Connector 2 (bottom). Accessory Connector 1
(RJ45) is used to connect to a Gold Series Elite Console via the ACIM.
The optional VU meter/clock provides a transmit audio level indicator and a
digital clock display. Power is provided to the VU meter/clock as soon as the
Consolette is plugged into a live AC outlet.
A fan is provided with every Consolette. It circulates the air inside the
Consolette to keep the internal ambient temperature at an acceptable level. It
is important for the fan to be operating at all times to maintain proper
Consolette operation. In addition, it is important to leave the top cover in place
to maintain proper thermal conditions inside the Consolette.
The location of the control head, Power On LED, VU meter/clock, and speaker
are indicated on the front panel of the station shown in Figure 6.

If any external equipment is inadvertently connected
to the wrong accessory connector, damage to the
equipment may result.
