ZETRON 37-MAX Installation Manual page 4

If this is your first Model 37-MAX Repeater Pal, your first questions probably are "What do I
have to do to enable a tone?" and "Do I have to understand all the features just to make it
work?" Here are the answers:
Before you can work with the Model 37-MAX, it must be installed. FOLLOW THE
INSTALLATION INSTRUCTIONS (see Section 5). The installation should be accomplished
by a qualified radio service technician. Then get your transceiver (set on the repeater's
frequency and with touch-tone keypad) ready to enable some tones.
To access the program mode, key up and press "12037". A chirp should be heard coming
back from the repeater (the chirp, or five beeps, is the "go-ahead" prompt tone). If the
program mode is not accessed, check the Status LED on the front panel to see if it flashes
with every key pressed.
During programming, the Model 37-MAX will issue prompt tones to indicate how it's doing.
A "warble" or "dee-doo dee-doo dee-doo" tone indicates an invalid command or that an error
condition exists. A "chirp" or "bip bip bip bip bip" (five quick notes) indicates the proper
completion of a command. A double "bip" indicates the panel is ready for additional digits to
be entered to complete a command. When exiting the program mode, a "ringing" sound will
be sent to verify the exit. If a key is not pressed within 60 seconds, the Model 37-MAX will
exit the program mode automatically.
A CTCSS tone may be enabled by pressing "111# nn#", where "nn#" is the tone number
from the User Numbers versus CTCSS Tones table in the Quick Reference section at the end
of this manual.
Enable CTCSS tones 67.0, 100.0, 127.3, and 186.2:
1. Access the program mode. Press "12037", then listen for the five beeps.
2. Enable the tones.
for 67.0 Hz (tone 1), press 111# 1# (five beeps heard)
for 100.0 Hz (tone13), press 111# 13# (five beeps heard)
for 127.3 Hz (tone 20), press 111# 20# (five beeps heard)
for 186.2 Hz (tone 36), press 111# 36# (five beeps heard)
3. Exit the program mode. Press 99#, then listen for the ringing sound to verify exiting.
