4 Other Functions and Options
4-1 Checking for Low
Power
The power low LED, used to indicate low power supply
warning, is provided on the indicator panel at the left side of
the lens, as viewed from the camera.
According to the supplied voltage, LED indicates:
Lit red: 10V or less
Off: Supplies sufficient voltage
So, when the LED is lit red, countermeasures to raise the
supply voltage to 10.5V or above is necessary. Otherwise,
the lens may malfunction.
POWER LOW LED
4-2 Using an External
Power Source
An external power input jack is provided at the right
side of the lens, as viewed from the camera. In case the
combination of portable camera and the lens with semi
or full servo operation, 12V DC (11-17V DC) should be
supplied to the lens through this jack since portable camera
does not have enough power consumption to drive semi or
full servo operation.
External Power Input Jack
Use a plug complying with EIAJ RC5320A TYPE4
specifications.
4-3 Heater System
(Option)
The heater system for warming up the lens to prevent
clouding inside the lens can be mounted on the lens. The
heater system is operated as follows.
1
Set the heater ON/OFF switch, which is located on the
right side of the lens as seen from the camera, to the
ON position.
2
To shut down the heater, set the heater ON/OFF
switch to the OFF position.
Heater ON/OFF Switch
* (NOTE)
A great deal of power is consumed when the heater switch is ON.
For this reason, the circuitry is designed to disable servo zoom
operations and servo focus operations.
To perform servo operations, stop using the heater.
4-4 Wiper System
(Option)
Checking the wiper power
Check that the power switch of the wiper is set to “ON”.
