Troubleshooting
Tote-Remote User’s Manual, Page 19
Solution: Take off the battery cover and snap it back into place again. If
the laser beam is still not performing well, replace the battery. The
Tote-Remote uses one CR 2032 lithium coin cell battery (available at
stores such as Radio Shack).
PROBLEM: REMOTE CONTROL WORKS BUT LASER BEAM
DOES NOT WORK AT ALL
Possible Cause: Laser pointer function may be disabled.
Solution: The Tote-Remote has a laser pointer disable function. See the
Features & Operation section of this user’s manual.
PROBLEM: REMOTE CONTROL DOES NOT WORK FROM
FAR AWAY
Possible Cause: Obstructions/interference.
Solution: Although line-of-sight is not required for sending radio
frequency signals from the remote control to the receiver, signal
strength and effective transmission distance may vary depending on the
relative locations of the remote control, receiver, and computer, and
also depending on other environmental factors such as walls and
furnishings. Sometimes range can be increased by plugging the receiver
into a USB extension cable that extends in front of the computer, or
turning the computer around, since the electronics inside the computer
may weaken the remote control’s RF signal if the signal has to pass
through the computer to reach the receiver.
