CHAPTER 3 SRP OPERATION
Short Range Programmer VRT—User Guide Page 13
P/N 52806T100 Rev 1 April 2003 • AMCO Automated Systems
• For V9 and VRT transponders which were interrogated in Find
mode, the compensation factor also displays on the lower line:
• If the interrogation is NOT successful,
the screen will display the
“CARRIER NOT DETECTED” message (indicating no signal
from transponder) or “RECEIVE DATA ERROR” (indicating radio
signal interference). This message displays for 2 seconds, during
which time the SRP will not interrogate.
5. If the interrogation is NOT successful, move the SRP to a slightly
different position relative to the transponder (closer, farther away, or
to one side) and interrogate again.
• Radio waves can bounce off of, or be absorbed or deflected by,
various materials (especially metals) which can create slight
differences in signal strength from one spot to another.
Using Program Index (and CF) Mode
This mode programs the current meter index value and compensation
factor (V9 and VRT).
NOTE: The compensation factor may be programmed only if the
transponder firmware supports CF and this can only be determined if the
transponder was interrogated first in the Find mode.
1. Press the MODE button repeatedly until the display shows either of
the following two Program Index (and CF) screens:
• For transponders accessed directly in Program Index (and CF)
mode:
