Warning
• Before connecting or disconnecting the antenna, ensure anti-static precautions are observed.
• RF512 survey transmitters contain a C-size lithium cell. This cell must not be incinerated or
subjected to temperatures in excess of 100°C. Do not deform, mutilate, crush, pierce,
disassemble, recharge or short circuit. Such abuse can result in loss of seal, and/or cell
explosion. Also exposure to humid conditions for long periods should be avoided.
• Do not insert metal objects into connectors.
• Ensure the antenna is securely connected before powering the equipment. Internal damage
may result otherwise.

than 7dBi are strictly prohibited for use with this device. The required antenna impedance is 50
Ohms. If in doubt please contact Comark or Distributor for advice.
• The RF505 Gateway have been designed to operate with the standard antenna supplied by
Comark, and having a maximum gain of 2dBi. Antennas not supplied by Comark or having a
