1.4 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 V50-60 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 2hours 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 aswitched-on
condition
·Use only AC networks in the range of 110-220V. Remember -the device supplied with AC
voltage with afrequency 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 aload (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, immediately 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

·Always take great care when moving or transporting the transceiver
·Maintain aminimum distance of 10cm between the cooling vents of the transceiver and
another object
Never cover the cooling vents which must always be open to allow sufficient ventilation.
Failure to do so may cause malfunctions
·Be careful to avoid dropping metal objects (screws, clips, metal filings, etc.) through the vents,
which may cause damage to the transceiver
·Always disconnect the antenna from the MB1 when not in use, or if there is adanger of
atmospheric electricity
·Ground the antenna-mast and antenna-feeders to avoid accumulation of atmospheric static
electricity on them
·Always use ferrite beads on antenna and other cables, connected to the transceiver
·Ensure the MB1 and any connecting cables are free from the effects of electromagnetic
interference and uncontrolled currents and voltages
·To avoid damage to the MB1 or causing harmful interference on air, it should only ever be
operated by competent persons
·Keep the MB1 out of the reach of children

2.1 Antenna
Before connecting the antenna, check the integrity of the antenna-feeder path.
For best results, the antenna should have an impedance of 50 Ohm to match the 50 Ohm
impedance of the HF nodes of the transceiver.
The antenna should have SWR level not worse than 1.5:1. If the SWR is worse than 1.5:1,
match the cable and the antenna to the desired level and/or use an ATU.
Note:
( Using amismatched antenna-feeder path might cause non-linear distortion of the transmitted
signal, HF interference on the transceiver's cables and/or interference of TV's or other
devices.
( Transmitting using areceiving antenna may damage it.
Warning!
iAlways use E-type ferrite beads on antenna and other cables, connected to the
transceiver!
2.2 Grounding
To eliminate the risk of electric shock it is essential to use areliable grounding connection for
the transceiver.
Warning!
iNever use water or gas pipes for grounding!
iNever use the MB1 transceiver without reliable grounding!
2.3 AC power
Connect the transceiver to the AC mains network with the power cable supplied with the
transceiver. Make sure, that the power outlet has the grounding/earth terminal and that it
matches the type of the power cable in use.
Warning!
iIt is recommended to set the E-type Line Filter on the Power Supply cable near the rear
panel of the transceiver.

2.5 Rear Panel
2.5.1 Accessories
You can connect several accessories to the transceiver's rear panel, as shown on the picture
above.
PTT Footswitch. Connects to the PTT socket and controls transceiver's TX mode. Connector
type -6.3 mm Jack.
When you press the footswitch, PTT Line connects to the Ground (Case), it causes the
transceiver to switch into the TX mode. Ared LED TX indicator on the front panel and in the
software window, indicates that the TX mode is on.
Releasing the footswitch returns the transceiver to the RX mode.
Straight Key. Connects to the KEY socket using the mono 6.3 mm Jack. Pressing the key
switches the transceiver to the TX mode and when closed generates acontinuous CW signal
(manual mode). The key is manipulated according to the message required.
Releasing the straight key returns the transceiver to the RX mode.
