Safety Information
WARNING
electric shock.
¾ NEVER operate the radio transmitter without a suitable artificial load or antenna connected
¾ DO NOT allows children to operate transmitter-equipped radio equipment.
CAUTION
¾ DO NOT operates the transceiver near unshielded electrical blasting caps or in an explosive
atmosphere unless it is a type especially designed and qualified for such use.
¾ NEVER modify a transceiver or accessory except as instructed in the service manual,
engineering bulletins or formal communication as this may invalidate any warranty, guarantee or type approval.
¾ NEVER use the transceiver in an aircraft.
¾ NEVER use the transceiver near to sensitive medical equipment or in areas where instructed
not to do so, e.g. Petrol filling stations.
¾ NEVER mount the transceiver unit on or near the Airbag or Airbag activation device.
¾ NEVER use an accessory not recommended or supplied by Maxon may cause damage to
equipment or injury to personnel, and will invalidate warranty.
¾ DO NOT use or place the transceiver in areas with temperatures below -30°C or above
+60°C, In areas subject to direct sunlight, such as the dashboard.
¾ AVOID placing the transceiver in excessively dusty environments.
¾ DO NOT fit the transceiver in such a manner that the antenna is next to, or touching,
exposed parts of the body, especially the face or eyes, while transmitting.
¾ ALWAYS Install the SD170E using a suitable heat sinking surface.
¾ NEVER operate the radio transmitter without a suitable artificial load or antenna connected.
¾ ALWAYS Secure locking nuts on DB09 connector and always disconnect power supply before
removing D-type connector.
For service or repair always return your radio to an authorised Maxon Dealer or warranty
conditions will be invalid.

About your SD170E Series data radio
About Your SD170 Radio
The SD-170E Series of RF Link Modules utilize the latest technology in their designs and manufacturing. SD-170E models are Phase Lock Loop Synthesizer (PLL)/microprocessor controlled, and offers 1/ 5 watt (Low/High) programmable output power with 16-channel capability. Multiple functions including 1200 to 9600 baud rates, AC and/or DC audio coupling, in these fully programmable RF Link Module units, to use FSK GMSK and FFSK modulation optional boards are provided. Programmable sub-audio squelch system (CTCSS & DCS) and two-tone squelch system are added to the signal level detect squelch system (RSSI). GPS Data handling is provided to interface and control an internal GPS receiver (optional board).
To assure satisfaction from the radio, we urge you to thoroughly read the operation and function information in this manual before operating your SD-171E/SD-174E.
Applications of some of the functions described in this manual are determined by the system you use. Your dealer will program your radio so that you have the greatest number of functions possible relative to your needs.
Should you have questions regarding the operation of the radio, please consult your Dealer.
