Notes on Use

Use and storage locations
Avoid using or storing the unit in the following places:
• Where it is subject to extremes of temperature (operating
temperature: 5 °C to 40 °C (41 °F to 104 °F)). Note that in
summer the temperature in a car with the windows closed
can reach 50 °C (122 °F).
• Very damp or dusty places.
• Where rain is likely to reach the unit.
• Places subject to severe vibration.
• Near strong magnetic fields.
• Near transmitting stations generating strong radio waves.
Avoid violent impacts
Dropping the unit, or otherwise imparting a violent shock to it,
is likely to cause it to malfunction.
Do not cover with cloth
While the unit is in operation, do not cover it with a cloth or
other material. This can cause the temperature to rise, leading
to a malfunction.
After use
Set the POWER switch on the CCU to the OFF position.
Care
If the body or panels of the unit become dirty, wipe them with
a dry cloth. For severe dirt, use a soft cloth steeped in a small
amount of neutral detergent, then wipe dry. Do not use volatile
solvents such as alcohol or thinners, as these may damage
the finish.
Low-loss Digital Transmission via
Multi-core Cable
Digital data transmission between the camera and CCU
minimizes image degradation regardless of transmission
distance. However, some errors, for example errors due to
external noise in long-distance transmission, may be
corrected by partial image interpolation of images in frame
store.
Multi-core transmission distances
The transmission distance allowed for Sony CCZ-A multi-core
1)
cable connections is between 5 m and 100 m
may decrease depending on the conditions, such as cable
degradation.
1) CCZ-A5/10/25/50/100 cable
2) Based on a single CCZ-A100 cable used. Transmission range
may vary when more than one cable is used.
Notes on using cable extension connectors (CCZZ-1E,
CCZZ-1B):
Avoid using more than three connectors at the same time.
Transmission range may decrease by 10 m when one
cable connector is used.
Examples of cable connection
An equivalent cable length of up to 100 m is approved. With a
length of more than 100 m, losses in the cable will not be
compensated properly.

Error Messages

When an error is detected in the CCU or the camera, the
ALARM indicator turns on and an error message is displayed
on the CCU.
