and +40C, and relative humidity in the 20-80% range. Operation outside of this range may cause damage to the
unit.
1.2 Licensing
This product operates in the commercial two-way radio communications band. A license to operate on a
particular frequency must be obtained from the FCC. Use form 600 to apply for a license to operate this unit in
your area. Operation of this product must be in compliance with the applicable FCC rules and regulations. In
most cases, the FCC Rules and Regulations are covered in Title 47 of the CFR, part 90 pr Part 22. Form 600 is

This product is Certified for use under FCC Parts 22 and 90. Internal circuitry may not be modified.
Modification of circuitry within this unit may void your authority to operate the equipment.
1.3 Radio Communication Interference
The OSMAC BaseOSMAC Base generates and uses high-frequency radio energy which can cause interference if not installed in
accordance to the user manual and using sound radio system engineering practice. For best results, it is
recommended that a qualified radio service technician install and configure the OSMAC BaseOSMAC Base.
The OSMAC BaseOSMAC Base has been tested and found to comply with the limits for a Class A computing device pursuant to
Part 15 of the FCC Rules and Regulations. Operation of this device in a residential area is likely to cause
interference in which case the user must, at his own expense, be required to take whatever measures may be
required to correct the interference.
1.4 Locating the OSMAC Base
The OSMAC BaseOSMAC Base is designed to sit on a desktop. Although this is a good location for ease of operation, it is
usually not the best place to locate the antenna. For most installations, it is recommended that the antenna be
located away from the unit, and high enough to provide good coverage. "Base Station" type antennas will
provide much better coverage than will the "rubber duck" type antennas. This is particularly true if an external
keyboard is to be used, since many keyboards malfunction in the presence of strong RF fields.
The LCD's contrast may be adjusted through a small hole in the rear of the unit. If the LCD is difficult to read
adjust its contrast with a small flat-bladed screwdriver.
1.5 Unit Setup
a) Connect the antenna or antenna cable to the BNC jack on the rear of the unit.
b) If you are using the OSMAC BaseOSMAC Base with a computer system, connect the computer's RS-232 port to the lower
serial port on the rear of the unit.
c) If you are using an external keyboard, connect it to the PS-2 keyboard jack at the rear of the unit.
d) If the telephone interface will be used, connect a telephone line to the RJ-11 jack on the rear of the unit.
e) Connect the DC power supply to the OSMAC BaseOSMAC Base. It connects to the large DIN connector on the rear. Plug
the external DC supply into an AC wall socket. Turn the power to the unit ON.
f) Configure the unit if necessary using the Configuration Mode.
