Section 1. Introduction
1-2
A Courtesy Beep, to inform listening mobiles that the speaker has definitely unkeyed, is
available on a per tone/code basis. The pitch of the Courtesy beep is also programmable (on a
system-wide basis) to either 500 Hz, 1000 Hz, or 1500 Hz.
The Reserved User feature helps to prevent the loss of tones or codes to co-channel operators
during periods when they are temporarily not in everyday use. When a tone or code is
programmed as ‘reserved’, the Repeater Pal will mute its repeat audio and transmit an alert
tone on the channel.
The Cross Tone encoding feature expands the uses to which the panel can be put, allowing it
to support applications that require the panel to encode a different tone or code than it
received.
Programming and Control
In order to make it easy to install and easy to maintain, the Model 37-MAX is designed to be
programmed over the radio channel using any mobile or handheld capable of manual DTMF
encoding. If you wish to, you can use a Zetron Model 8B Repeater Programmer/Timekeeper
attached to a control station or mobile radio.
This programming method was chosen for two very good reasons. First, because it doesn’t
require the installer or maintenance technicians to have special equipment in order to
program the repeater; they can use equipment they already have. The second reason is that
you don’t have to be physically at the site in order to program the repeater. All the technician
needs to be able to do is to drive far enough into the repeater’s service area to be able to
reliably hit the repeater while programming it. This can pay real dividends when a trip to the
site is made difficult not just by distance but by accessibility as well.
Installation and Setup
Easy installation and setup procedures ensure that a technician can install a Model 37-MAX
in nearly any repeater or duplex station. Only seven connections are required in typical
installations, and interfacing assistance is available from Zetron. Section 5 includes
