Concerning the Remote Control
This unit has three systems for remote control operation, using the infra-red remote sensor, the 8-pin parallel
input terminals or GPI input terminal.
Remote Control Transmitter
Battery installation
Insert the batteries with using two IEC R03, AAA, UM-4 (1.5 V) or equivalent batteries in the correct polarities
(+, -).
To remove the batteries, push down the — side.
Notes:
* Do not mix old and new batteries, or batteries of different types (manganese and alkaline, etc.).
¢ Never subject batteries to excessive heat or flame; do not attempt to disassemble them; and be sure they
are not short-circuited.
° If the remote control is not to be used for a long period of time, remove the batteries and store them ina
cool, dark place.
* Do not attempt to recharge alkaline or manganese batteries.
Battery life:
The battery life is about one year. The batteries should be replaced if commands from the remote control
transmitter do not operate the unit even when the transmitter is held close to the front panel.
Correct method of use
1 Aim the remote control's transmission window toward the unit's sensor. Avoid any obstacles.
2 Use the remote control within a 60-degree angle of the unit.
The maximum distance is within 7 meters directly facing toward the unit.
Notes:
¢ Be sure the transmission window and the unit's sensor are free from dust. Excessive dust might affect its
performance.
¢ The operation may not be correct if direct sunlight or other strong light source strikes the receiving sensor
of this unit. If there is a problem, place the unit away from the light source.
¢ If this unit is installed in a rack with glass doors, the glass doors' thickness or color might make it
necessary to use the remote control a shorter distance from the unit.
8-Pin Parallel Input Terminals
By connecting the following circuits, the SV-4100 can be operated by remote control using normal switches.
