Pelco Manual C671M (1/01) 51
ADDITIONAL FUNCTIONS AND FEATURES
COUNTER
TAPE COUNTER
A five-digit counter indicates the relative position on the recorded portion of the tape.
COUNTER RESET
Press the COUNTER RESET button to reset the counter to 00000.
COUNTER MEMORY
The counter display is stored in memory when the power is turned off, so the same
numbers are displayed when power is restored. (Refer to the
Counter Memory Stop
section
for information and procedures for rewinding to 00000.)
MEMORY BACKUP IN CASE OF POWER FAILURE
The VCR includes a built-in memory backup so the settings for time and date, alarm list,
power loss list, number of tape uses, counter display, and recording/playback mode will
remain in memory if there is a power failure or the power cord is unplugged for a long
period (two-three months). The settings remain in memory for up to 31 days provided the
VCR has been connected to AC power for at least 40 hours per week. Connection charges
the battery backup.
However, if the power cord is unplugged for a long period (two-three months), the time may
be wrong. If so, set the clock again.
When ALARM REC DURATION in the Recording Set Up menu is set to MAN1 or MAN2
and the power fails during recording, the VCR may not return to the alarm recording mode
when power is restored.
TESTING
INITIAL SYSTEM TESTING
Before using the newly installed surveillance system, do the following:
Make test recordings at the time-lapse speeds you will be using. Test how the system
performs with alarms.
Interrupt electrical power to check your installed power backup system (if applicable).
On playback, verify picture quality and that you can see the time and date display under
normal and alarm conditions.
REGULAR SYSTEM TESTING
Every day check that the system is operating. Is the recording indicator lit? Does the
counter display indicate movement? Does the monitor show proper camera sequencing
and time and date information?
Check for recorded alarms. Multiple alarms could make the tape run out early. Make sure
there is enough tape to record at least five minutes of alarm activity at the selected speed.
Regularly verify picture quality and operation under normal and alarm conditions. Play a
tape recorded recently under normal conditions, which also includes an alarm condition that
you triggered manually.
Regularly replace tapes (refer to Table B for a schedule). Check tapes for head scarring.
Replace damaged tapes. Always store tapes in their boxes, away from magnetic fields,
heat, direct sunlight, and dust.
NOTE:
The backup is for
memory only—the VCR will
not continue recording dur-
ing a power outage unless
connected to a UPS.
