D Coin cell battery cautions
R DANGER! The controller contains a coin cell
battery. NEVER swallow the battery.
This could cause severe internal burns in just 2 hours,
and could lead to death.
Keep new and used batteries away from children.
Also, DO NOT use or leave the transceiver with the
controller case open (the battery compartment is
easily accessible). It must be away from children.
If the battery might have been swallowed or placed
inside any part of the body, immediately go to the
doctor.
R WARNING! NEVER charge, short-circuit,
disassemble, deform, heat, or incinerate the coin cell
battery. The internal ammable materials may cause
them to overheat, explode, or catch re.
R WARNING! NEVER solder the coin cell battery
terminals. This may cause them to overheat, explode,
or catch re.
R WARNING! When disposing of batteries, wrap the
terminals in tape to insulate them. Shorting may occur
if the terminals touch metal objects. This could cause
them to overheat, explode, or catch re.
Dispose of used batteries in accordance with local
regulations.
R WARNING! NEVER reverse the coin cell battery
polarity. This could cause a re or damage the
transceiver.
R WARNING! NEVER leave the coin cell battery in
places with direct sunlight, high temperature, or high
humidity. This could cause a re.

For amateur base station installations it is recommended
that the forward clearance in front of the antenna array is
calculated relative to the EIRP (Eective Isotropic Radiated
Power). The clearance height below the antenna array can
be determined in most cases from the RF power at the
antenna input terminals.
As dierent exposure limits have been recommended for
dierent frequencies, a relative table shows a guideline for
installation considerations.
Below 30 MHz, the recommended limits are specied in
terms of V/m or A/m elds as they are likely to fall within the
near-eld region. Similarly, the antennas may be physically
short in terms of electrical length and that the installation will
require some antenna matching device which can create
local, high intensity magnetic elds. Analysis of such MF
installations is best considered in association with published
guidance notes such as the FCC OET Bulletin 65 Edition
97-01 and its annexes relative to amateur transmitter
installations. The EC recommended limits are almost
identical to the FCC specied ‘uncontrolled’ limits and tables
exist that show pre-calculated safe distances for dierent
antenna types for dierent frequency bands. Further
information can be found at http://www.arrl.org/.
• Typical amateur radio installation
Exposure distance assumes that the predominant radiation
pattern is forward and that radiation vertically downwards
is at unity gain (sidelobe suppression is equal to main lobe
gain). This is true of almost every gain antenna today.
Exposed persons are assumed to be beneath the antenna
array and have a typical height of 1.8 m.
The gures assume the worst case emission of a constant
carrier.
For the bands 10 MHz and higher the following power
density limits have been recommended:
10–50 MHz 2 W/sq m
Vertical clearance by EIRP output
1 Watts 2.1 m
10 Watts 2.8 m
25 Watts 3.4 m
100 Watts 5 m
1000 Watts 12 m
Forward clearance by EIRP output
100 Watts 2 m
1000 Watts 6.5 m
10,000 Watts 20 m
100,000 Watts 65 m
In all cases any possible risk depends on the transmitter
being activated for long periods. (actual recommendation
limits are specied as an average during 6 minutes)
Normally the transmitter is not active for long periods of
time. Some radio licenses will require that a timer circuit
automatically cuts the transmitter after 1–2 minutes etc.
Similarly some types of emission, i.e., SSB, CW, AM etc.
have a lower ‘average’ output power and the assessed risk
is even lower.
