DVR Programming
The following paragraphs provide detailed DVR programming information.
IMPORTANT!
Do not change DVR settings unless fully familiar with the meaning of a specific
option. The Tweaker program reports any obvious errors and does not allow invalid
data to be saved to the DVR, however, not all inconsistencies can be reported by
the Tweaker. Successful DVRS programming requires thorough understanding of
the DVR, MSU and PSU programming as well as the specific User / System
requirements. Only when all templates (DVR, MSU and PSU) are matched, the DVRS
will operate properly. For instance, changing the APX MSU template may require
corresponding update of the DVR template, which in turn may require update of the
PSU template.

possible
– Set 1 and Set 2, which can be either Narrowband (12.5kHz) or Wideband
(25kHz). Ensure the correct spacing (Set 1 or Set 2) is selected to match the portable
radio programming on each DVR channel
– see “Repeater Channel Setup” screen,
‘Bandwidth’ field.
