Precautions
To prevent damage to the transceiver, please read these operating rules carefully before
attempting to operate the transceiver.
·
Carefully read this manual first, otherwise connecting and operating the MB1 could lead to the
fatal errors
·
Before connecting the device to the AC network 110-220 V 50-60 Hz, visually inspect the MB1
for the absence of mechanic damage
·
DO NOT use the MB1 in temperatures lower than 0ºC (32ºF) and higher than +60ºC (140ºF)
·
If the MB1 was stored in abnormal climatic conditions, it is recommended to keep it in normal
operating temperatures for at least 2 hours before switching on
·
Before connecting the MB1 to the AC power line, ensure it is grounded. Never use the MB1
transceiver without grounding!
·
Before connecting external devices read the Connections Section
Note, the MB1 output switches are limited to the values of the supply voltage and the current
passing through them, do not allow polarity reversal
·
Only connect external devices to the MB1 in accordance with the wiring diagrams shown in
this manual
·
Never connect external devices to the MB1 transceiver which are live or in a switched-on
condition
·
Use only AC networks in the range of 110-220V. Remember - the device supplied with AC
voltage with a frequency of 50-60 Hz
·
Never use or store the MB1 in dusty rooms, nor allow prolonged exposure to direct sunlight
·
Avoid the exposure of the atmospheric downfalls on the MB1 and never spill any liquids
(especially aggressive) on it
·
Do not emit HF/VHF signal with power more tan 1W in the same room or near the MB1
transceiver
·
Do not open the MB1. It contains radio components, which are highly sensitive to static
electricity. For any repairs to the product please contact the manufacturer
·
Do not transmit without a load (dummy load/matched antenna) - this will lead to overheating
of the active output devices, and possibly cause their thermal breakdown. The same applies to
an unmatched load
·
If the transceiver emits an abnormal odor, or smoke, immediat ely turn it's power OFF and
remove the power cable. Contact the nearest Expert Electronics dealer for advice
·
Never stand the transceiver on the front or rear panel - this may lead to damage of the
controls and/or the display
