Pelco TLR3168 operation manual Index Search, HOW to Count the Index Number

INDEX SEARCH

The VCR automatically inserts an index signal at the beginning of each alarm recording, so the start of each alarm can be located. During fast forwarding or rewinding, the VCR can search for an alarm index signal you have selected. When the VCR finds it, the VCR plays back the tape in still mode.

1.Press the SEARCH button enough times to highlight INDEX SEARCH on the Search Function menu. The index search indicator (INDEX) on the fluorescent display lights.

To exit the Search Function menu without searching, press STOP.

2.Turn the JOG dial to select an index number (between 1 and 255) you want to find.

3.Turn the SHUTTLE ring right (search forward) or left (search backward) to start searching. The index number in the fluorescent display decreases by one as each index signal goes by.

4.To quit while searching, press STOP.

The index signal may be hard to find under some recording conditions. Index search may not function if the interval between two alarm recordings start times is too short. Refer to Table G for minimum intervals.

HOW TO COUNT THE INDEX NUMBER

The index number is the count from the present position. The index number of one alarm recording before the present position is –1. The index number of one alarm recording after is +1.

The maximum count of alarm recordings is ±255.
