When to Change:
The internal 9 volt battery needs replacing when the indicator LED is
no longer visible when any button is pushed. The operating range of
the remote will gradually decrease. When the range is insufficient for
your normal mode of operation, replace the battery (even if the LED is
still visible).
Installing/Changing:
1) Turn the remote unit over. Remove the three phillips screws
with a number 2 phillips head screwdriver.
2) Turn the unit right side up. Pop the front panel out by
applying pressure to the lower left corner of the blue urethane
case thus exposing a corner of the front panel / switch
assembly. With a flat screwdriver blade; carefully pry out the
switch from the urethane case by working the screwdriver up
the left edge of the switch assembly. Be careful not to insert
the screwdriver too deep as you may damage the internal
electronics.
3) Fold the switch assembly to the left side of the unit, exposing
the battery and the printed circuit board.
4) Pull the battery connector off the battery. Remove the battery
by tilting it up sideways.
5) Install the new battery by tilting it in sideways and wedging it
in the small indented region between the printed circuit board
and the case wall.
6) Reconnect the battery connector. Check for operation by
pushing any key on the front panel and ensuring that the
indicator LED is lighted. If it does not, check that the
keyboard connector is still seated properly and the battery is
fresh.
7) Replace the front panel / switch assembly by centering it over
the open area and pressing evenly around the edges until it
seals.
8) Replace the three screws. Make sure the screw seal gaskets
are in good condition.
Infrared Remote Comments:
• Due to the sensitivity required to allow for full sunlight
operation, it is possible to overload the input to the infrared
remote receiver in the scale if the remote is too close. This
situation is characterized by erratic remotely controlled
operation. The simple remedy for this is to not aim directly at
the scale, but aim slightly off center when very close.
