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.

Repeater Pal is in control. The 37-MAX recognizes when a subscriber unkeys with a reverse burst, or the DCS turn-off code, and silently mutes the repeat audio path to prevent bursts of “squelch tail” noise from being repeated on the channel.
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.
Sections 3 and 5 before starting to work with the unit. Depending on your level of experience with Zetron’s other tone panels, you may want to review the Section 4 as well. This manual contains the following sections: 1.

Section 1. Introduction 5. PROGRAMMING Provides background information on entering and exiting the program mode. It also provides in depth explanations of the programming commands and tables of tone frequencies and DPL codes showing their relationship to user numbers. 6.

USERS VERSUS CTCSS/DCS DECODE Since the Model 37-MAX is a multi-user repeater tone panel, it behaves as though it had a separate decode/encode module for each user group it supports. In reality, this is achieved using a single microprocessor controller and some very smart software to run it.
Disabled Users The default condition for all users is disabled. The 37-MAX will still be able to decode these tones and codes, but it will not react to them in any way. If a user has been previously enabled and programmed, the user can be disabled without altering any of that programming.
(sometimes called "carrier controlled repeat", "carrier squelch", or an "open repeater"). When this mode of operation is enabled, the 37-MAX will allow any user to bring up the repeater, regardless of any encode. Users with CTCSS or DCS encode will be treated as the Carrier Repeat user if this mode is enabled.
When an ENABLED user is placed in this mode, the panel will still key upon decoding that tone or code, but it will not pass audio. Instead, the 37-MAX will transmit a beep tone to indicate to anyone monitoring the channel that a reserved tone is in use. The panel will still encode the proper CTCSS tone or DCS code for this user.
(in whole minutes), with the default being 15 minutes. ID Mode = The 37-MAX can be set to not ID at all, to ID only when the timer has expired and there has been recent activity on the repeater, or to ID automatically whenever the timer expires regardless of whether there has been any recent activity or not.
Reserved Mode Users If the tone or code decoded by the 37-MAX during a transmission belongs to a user that has been placed in the Reserved mode, then the panel mutes the repeat audio path and transmits a covering beep tone to let anyone monitoring the channel know that a reserved user has been brought up.
DCS codes are inverted, then they will all be inverted. The 37-MAX has two complementary sets of commands in its system programming that will independently configure the DCS decoding and encoding done by the panel to be either 'normal' or 'inverted'.

If the access code decoded by the 37-MAX is invalid, then the panel will ignore the attempt. Manually Resetting the Access Code There are a number of ways in which the Program Mode Access Code in use can be rendered useless;...
“99#”. The 37-MAX will transmit a prompt that sounds like the ringing of an electronic telephone, and then return to its normal, idle state. If the Model 37-MAX receives no new commands for a period of 60 seconds, it will exit the program mode and return to the normal idle state on its own.
Enable and Disable a User In order to enable service to a particular tone or code in the Model 37-MAX, the user number associated with that tone or code must be enabled. The two commands shown here are used with the appropriate user number to start or suspend service.
Reserve Mode Enabled for User “uu” Courtesy Tone The Courtesy Tone is a beep prompt transmitted by the 37-MAX every time it detects that the mobile which was transmitting has unkeyed. This provides a positive indication to the listener that the transmitting mobile has finished their last transmission, as opposed to just pausing a moment.
These commands are used to configure how and when the Morse code Station ID occurs, if this feature of the Model 37-MAX is being used (the default condition is ID with activity enabled). The panel can be set to only ID when the timer has expired and there has been some activity on the channel either during the timer period or since it timed out.

This command allows the service technician to invert the polarity of the DCS decode in software. This may be necessary to make the received data stream from the mobiles using the system look correct for the decoder in the Model 37-MAX. 217#...
Repeater Knockdown and Setup The Model 37-MAX can be disabled and then enabled again (without losing any of its programming) by using the Disable button on its front panel. These commands allow the technician to do the same thing remotely using DTMF commands.
When this command is entered, the 37-MAX will key the transmitter, open the repeat audio path, and then remain that way until the test is terminated. The technician will then transmit a signal of known level to the repeater and adjust the receive level and de-emphasis jumpers until a unity gain output is achieved on the transmitter.

Connections to the transmitter, receiver, and power supply are grouped on a detachable connector on the rear of the unit for ease of installation. The Model 37-MAX includes installation test modes to aid in installation. Adjustments can be made from the rear of the Model 37-MAX, though the top cover will need to be removed during the initial installation to allow the technician to check and set the positions of various jumpers.
4. Transmitter Audio Output: Connect a shielded cable from J1/pin-5 ( ) of the TX AUD Model 37-MAX to the microphone input of the transmitter. Connect the shield braid to J1/pin-6 ( ) of the Model 37-MAX, and leave it unconnected on the radio end.
TESTS AND ADJUSTMENTS These tests and adjustments will need to be done after the Model 37-MAX has been installed on the repeater and prior to programming the system and placing it in service. The tests need to be done in order to ensure reliable operation and optimum audio quality on the system.

6. Encode Output Level: To set the encode level, enter the DTMF command "395#". The Model 37-MAX will key the transmitter and encode a 136.5 Hz CTCSS tone. Adjust the potentiometer R1 to set the encode level at 15% of full channel deviation (example: that is ±...
Section 5. Installation ALTERNATE TEST AND ADJUSTMENT PROCEDURE There is another way to set up the Model 37-MAX on a new radio system that does not require having a radio with a DTMF encoder. Cycling the Model 37-MAX through the various test modes is accomplished using the Disable button on the front of the unit.
Page 41
Model 37-MAX. Some duplex capable radios disable their receivers while transmitting. If this is the case, the radio will need to be modified before continuing. 10. This completes the Alternate Test Procedure. Cycle power on the Model 37-MAX to return it to normal operation.
This subsection contains applications notes with connection information specific to some of the more popular repeater stations used with Zetron tone panels. Most of these notes were written assuming that Zetron's Generic Radio Cable (part # 709-7179) was used to do the interface, however, the same information will still be very useful to any technician that is making up a cable on site.
Set the CG Pot to 255 g. No CCT or DODT Timers (set to 0) h. Remote Control optional 3. Set the repeat and CTCSS modulation levels by adjusting the Zetron unit (See “Tests and Adjustments” earlier in this section.

Repeated audio from the Model 37-MAX will be heard in the local speaker of the R-100 if the 37-MAX's TX audio is connected to JAUX pin-5. This is because the audio at pin-5 goes to several points in the R-100 (Local Audio Amp, Exciter Board, and the Line Output) as well as the TX Command board.

4. The Carrier LED must follow carrier activity on the channel. If it is always off, the Model 37- MAX will not detect CTCSS tones. If it is always on, the Model 37-MAX will usually time out. The Model 37-MAX is a microprocessor controlled device, which means that the operation can change depending on the software the microprocessor is running.
