SWITCH

DESCRIPTION

Always hear the Race Officials over your Team Radio conversations. This is what the SWITCH

does.

The Racing Electronics SWITCH And SWITCH RACER combine a 2 Channels Radio Receiver

with an Audio Input Port and an Audio Output Port. The Audio Input Port is connected to the

output of your 2 way radio. It is internally looped to the Output Port where your headsets are

connected so that you normally hear the conversation with your Team. Messages from Officials

are detected by the built in Receiver and immediately routed to your headsets. When this

happens, your 2 way Radio Audio is attenuated. The frequencies of the 2 channels are Preset but

programmable.

The Switch is however fully versatile to be used different ways as follow:

1. The Audio from the Audio Input Port is not mandatory. If used, it will always be attenuated

when activity is detected on a Preset Channel. You can connect any audio source to that

port.

2. The Preset Channels can be used as follow:

a. Hold on Preset Channel 1 (Always the default at power ON. Fully programmable)

b. Hold on Preset Channel 2 (Fully programmable)

c. SCAN Preset Channel 1 or 2. (activity must finish on an active channel before

switching to other channel. Not available in SWITCH RACER)

d. SCAN with Priority on Preset Channel 1. (Channel 1 interrupts channel 2. Not

available on SWITCH RACER)

e. SCAN with Priority on Preset Channel 2. (Channel 2 interrupts channel 1. Not

Available on SWITCH RACER)

The SWITCH is shipped with Preset Channel 1 programmed at 454.0000 MHz, the frequency for

the NASCAR Officials. You can however reprogram the frequency to any of the available 12.5 Khz

bandwidth channels in the 450-470 MHz range. It is fully compliant with today’s Motor Racing

sanctioning body.

The SWITCH takes advantage of the Analog and Digital Squelch technology (DTCSS/CDCSS,

PL/DPL from Motorola

). Using that sub Channel technology insures that if a frequency is used

by more than one team, you can select to listen only to the one you want from its sub Channel

number.

The SWITCH generates distortion free audio, loud enough for the race environment. The Audio

Input Port accepts 1/8 jack, mono or stereo. Headsets with 1/8’’ mono or stereo jack can be

connected to the Audio Output Port.

The Switch Operates from 2 AAA batteries. Normal Alcaline batteries provide 7 hours of

continuous operation. A Battery Low indicator turns ON when you still have only 30 minutes of full
