1 Installation
1.1 Environment
The OSMAC Base is designed for an indoor office environment. Ambient air temperature should be
between -10 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 available at the FCC WEB site: http://www.fcc.gov/formpage.html. See appendix A
for a list of frequency coordinating agencies.
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 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
Base.
The OSMAC 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 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 used, as 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 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 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.
