Caution
Voltage on pin 9 must always be greater than the voltage at pin 5 (ground). Pin 5 is
electrically connected to the chassis ground (negative ground). Maximum current from
pin 9 to pin 5 is 50mA. Maximum voltage on pin 9 at any time is 32V (the same as for
the Tropos 4210 router.) Exceeding these maximums can damage the remote indicator.
