ZETRON 37-MAX Installation Manual page 24

Section 3. Operation
Fortunately, the Model 37-MAX has a Repeater Knock-down and a Repeater Setup
command. If the technician uses the Knock-down command and then exits the programming
mode, the panel will retain all of its programming, but it will not function and service the
valid radio users until the technician enters and exits the programming mode again, or the
main power is cycled. The Setup command is supplied so that the 37-MAX can be enabled
again after certain types of testing or so the Knock-down command can be canceled while
still in the programming mode.
