2.10.4 Accessing the Calibration Modes
1. On the top side of ThePoint, temporarily remove the shunt
from the “Time Delay Selection Jumper” (see Fig. 2) and
place it on pins 1 & 2 of the 3-pin connector. Pin 1 is closet
to the LEDS. The green LED will go out and the red LED
will begin to flash. The number of flashes indicates which
mode the unit is in (1 through 8).
2. To switch modes, press and hold the ReCal button next to
the 3-pin connector. The unit will cycle through the modes.
First it will flash the current mode setting, then progress
through all of the settings.
For Example:
The red LED will flash once indicating mode 1. Then it will
flash twice-indicating mode 2. Then mode 3, etc.
Release the button when it reaches the desired mode. The
red LED will now flash indicating which mode the unit is
in.
3. Remove the shunt from pins 1 & 2 on the 3-pin connector
and replace the shunt on the “Time Delay Selection Jumper”.
The unit will remain in the selected mode. Write the new
mode # on the inside of the lid label for future reference
4. After setting the mode follow procedure in section 2.8.2
for mode 2 & 6. For modes 7 and 8, follow the appropriate
manual calibration procedure as described in section 2.10.3.
