E/PROM PROGRAMMING
70-050/055
as detailed in the 70-1000 Operator's Manual.
The Busy Channel Lockout function, if programmed, prevents inadvertent
transmission on a occupied frequency and can be programmed to audibly
warn the operator that, transmission is not occuring. The BCL0 function
can be jumper selected to operate on carrier or CTCSS tone. The
standard radio is configured for carrier BCL0 by JP107. If tone BCL0
is desired, remove JP107 and install a jumper in the JP108 position.
DO NOT operate the radio with both JP107 and JP108 installed. Time Out
Timer programming is selectable from 30 seconds to 210 seconds as
detailed in the 70-1000 manual.
Note that for all radios programmed for either noise squelch scan or
CTCSS scan, the automatic default condition should be used for
function codes 3 and 4 (intervals A and B). These same default
conditions should also by used if no scan channels are programmed.
PROGRAMMING THE E/PROM MODULE
Carefully check the programming data entered in the buffer RAM of the
programmer for correctness by repeatedly pressing ENTER or by printing
out the buffer RAM contents on the 70-1300 printer.
Prepare the E/PR0M module for programming by a thorough erasure in the
70-1100 E/PROM Eraser. Plug the E/PR0M module in the programmer
adapter, noting the following precaution.
MAKE SURE THE E/PR0M MODULE CONNECTORS MATE PROPERLY WITH THE
ADAPTER PINS AND ARE NOT OFFSET IN EITHER DIRECTION.
Remove the module at the completion of the Blank Check, Write and
Verify operations. Reinstall the E/PR0M module in the transceiver,
again checking for proper mating of the connectors.
