1.3 Precautions

1. Never connect the unit to an antenna during a lightning storm and windy dry days.

Lightning strikes and static discharges can damage the unit and may kill the operator.

2. Static build-up on an antenna may cause damage to the unit when connected. As a

precaution, before pluging the coax cable into the analyzer always discharge the

antenna by momentarily shorting the center and outer conductors of the connecting

coax cable together and then touching the coax connector shell to the analyzer to

equalize the charge. After operation, always disconnect the antenna.

3. Maximum safe RF input is 2V peak (+16 dBm). Exceeding this RF level may damage

the unit. Note that powerful active transmitters nearby may induce a high RF voltage on

the antenna.

4. Test port is DC coupled. Use an external series capacitor for measurement scenarios

whereby a DC voltage is present.

5. This product emits a low power RF signal during its active measurement mode. When

connected to an antenna system, this radiation may cause interference to nearby

communication systems. Connect only for as long is necessary.

6. On first time use, it is recommended saving the factory files in a safe place. Please

connect the device to a PC via an USB cable and copy the files in the internal disk to a

location in your computer.

7. Please review carefully the instructions in Battery Maintenance and Safety Guidelines

section.

1.4 Battery Maintenance and Safety Guidelines

The internal Lithium-Ion rechargeable battery require routine maintenance and care in their use

and handling. Read and follow the guidelines below to achieve the maximum battery life span

and safely handle the battery.

1) Avoid extreme ambient temperatures

For a higher battery life span, the device should be operated in an ambient temperature range

between 16° to 25° C (62° to 77° F). It’s especially important to avoid exposing your device to

ambient temperatures higher than 35° C (95° F), which can permanently damage battery

capacity. That is, your battery won’t power your device as long on a given charge. Charging the

device in high ambient temperatures can damage it further. Also, never charge your device

unattended or in any place where there is a risk of fire.
