Important Precautions
Observe the following safety precautions to ensure user safety and maximizing the operating life
of the preamplifier.
Remove the batteries from the preamplifier when it is not used for an extended period.
Use only the battery charger adapter supplied with the preamplifier.
Replace fuse with same type and size.
To avoid risk of explosion replace batteries with same type specified in manual.
Exercise caution when handling the preamplifier because it is sensitive electrostatic
discharge.
Avoid using the preamplifier in environments with excessive heat or moisture.
The only user replaceable part in the preamplifier is the battery pack. It can be accessed from
the bottom of the unit. There are no other user serviceable parts inside the unit. Do not remove
the main instrument cover. If the preamplifier needs repair please contact authorized Com-
Power service center.
3.1
Excessive RF input
Do not exceed RF input level indicated on front panel. Excessive RF input may damage the
preamplifier’s sensitive input and will not be covered under warranty.
3.2
Saturation
In addition possible damage to the preamplifier input, excessive RF signals may cause the
preamplifier to saturate. When a preamplifier reaches saturation point the gain will reduce
and cause a nonlinear increase in output power resulting inaccurate measurements. PAM-
6000 can handle up to +2 dBm (105 dBµV) input signal.
3.3
Calibration
The factory recommended calibration period for the Preamplifier is 12 months. However, its
performance should be checked periodically to ensure the preamplifier is operating within the
rated specification given in section 2.0 of this manual.
