Important Usage Notes: Ensure Safe & Effective Civilian Operation
To maximize the performance and lifespan of your SZ Vodasafe P28 for civilian use, please adhere to the following guidelines:
Antenna Installation: Always connect all antennas (one-by-one) before powering on the device. Incorrect or missing antenna connections will severely reduce jamming coverage and may damage the device.
Charging Precautions:
Charge the battery for at least 8 hours before first civilian use.
Turn off the power switch before charging. The charging indicator will glow RED (charging) and turn GREEN (fully charged).
Do not use the device while charging - this may cause overheating (up to 75°C) and damage the charger or jammer.
Temperature Control: If the device temperature exceeds 60°C, turn it off immediately and contact your local SZ Vodasafe agent for assistance.
Interference Avoidance: Keep the device away from civilian electronic devices (computers, notebooks, televisions, audio equipment, and AM/FM radios) when powered on to prevent signal interference.
Battery Maintenance: The Ni-MH battery has a lifespan of approximately 500 recharge cycles. If the battery no longer holds a charge, contact a local agent for replacement.
Regulatory Compliance: Ensure the use of the P28 complies with local laws and regulations regarding signal jamming for civilian purposes. SZ Vodasafe is not liable for improper use violating regional civilian rules.
