Dittel FSG 5 Operating Instructions

Functional Checks
If the transceiver does not operate correctly, check the following:
• Is frequency with the two selector knobs correctly set?
• Is battery capacity sufficient? Carry out a battery test without any charger connected!
• Weak signals? Switch OFF the squelch!
• Is the transceiver's helical antenna vertically held or is it screened by the operator's body?
• Operate radio without any accessory. Same malfunction?
• Are helical antenna or antenna plug/ cable damaged?
• Is voice level too low or distance to microphone too far?
• Does multipath effect occur? Change location.
• At radio interference change location. Suppress interference of your car/airplane.
In case of doubt, compare operation of the transceiver with another transceiver on the same
location or call another station. Should the unit require service, please contact your nearest
authorized dealer or certified repair station.
Siting
The radio operates in the VHF frequency band, this is a Line-Of-Sight (LOS) frequency;
therefore, siting of the radio greatly affects its operating range. The longest range is normally
obtained when a direct LOS is maintained between the radios. Use of hilltop or tower loca-
tions will increase the LOS range. Location in valleys with intervening hills, behind buildings
or in dense woods may reduce or prevent communications. If possible, avoid locations near
electrical interference sources, such as power and telephone lines, computers, radar's,
welders and electrical generators.

Safety Information

Every radio, when transmitting, radiates energy into the atmosphere that may, under certain
conditions, cause the generation of sparks. All users of our radios should be aware of the
following warning:
Do not operate radio near flammable liquids or nearby explosive devices.
During normal use, the radio will subject you to radio energy substantially below the level
where any kind of harm is reported.
To ensure personal safety, please observe the following simple rules:
• DO NOT transmit when the antenna is very close to, or touching, exposed parts of the
body, especially the face and eyes.
• DO NOT transmit inside vehicles or aircraft with the helical antenna, always operate the
radio with a suitable external antenna. Assure appropriate lightning protection where ele-
vated outdoor antennas are used.
• DO NOT hold the transmit (PTT) key in when not actually desiring to transmit.
• DO NOT allow children to play with any radio equipment containing a transmitter.
• DO NOT operate the radio whilst driving. It should also be noticed that the use of a hand
held microphone while driving could constitute an offence under the Road Traffic Regu-
lations.
This radio contains a Ni-MH battery!
DO NOT dispose worn out Ni-MH batteries with domestic waste. Consumers are
obliged by law to return Ni-MH batteries at the end of their service lives to the
Ni-MH public collecting points set up for this purpose or point of sale.
