2.3 Security

Your MIDLAND transceiver is designed to give you maximum security and reliability. As with all electrical devices,
basic precautions should be followed in order to avoid damage to other objects or to people - including yourself and
your radio. Please see the following precautions:
2.3.a General precautions
• This device is to be used solely as an aid to work performance. Its settings may be affected by different factors, such as
defects or malfunction of the device, environmental conditions, or improper use.
• It is important to read – and follow – all of the warning labels and instructions placed on the device and its accessories.
• Do not open the transceiver for any reason, or attempt to repair it (with the exception of the routine maintenance described in
this manual). Unauthorized opening of the transceiver will nullify the warranty, and may cause damage that requires drastic
repair work. Please contact your local vendor for assistance.
• Do not let your radio get wet. If the transceiver happens to get wet, dry it as soon as possible with a soft, clean cloth. If you
think liquid may have penetrated HM35’s housing, see your authorized service center as soon as possible.
• Only use original accessories; anything else may seriously damage your transceiver.
• Turn off your radio before cleaning it. For cleaning, follow the instructions outlined in Chapt. 11.
• Pay attention to environmental conditions. Your radio was designed to be used in extreme environmental conditions, though
excessive heat or cold should be avoided.
• Operating conditions/usage
• Do not use the radio when driving. Driving regulations expressly prohibit the use of transceivers by drivers while the vehicle is
in motion.
• Do not operate the radio near shieldless explosives or in potentially explosive environments (e.g., in the vicinity of gas
stations). A single spark may cause an explosion.
• Do not approach the transceiver’s antenna during transmission. The radio functions at optimum levels when the microphone is
held at a distance of 5 to 10cm from the mouth, and when the antenna is installed at the centre of the roof, in a vertical position
and free from obstacles.
