Site Requirements
Ventilation
AT-MR420TR/AT-MR820TR Micro Repeaters have grilled openings
on both sides for ventilation. Although they do not require an internal
fan to aid in cooling, adequate ventilation is required. Ensure that the
ventilation openings located on the sides of the chassis are never
blocked.
Note
Maximum ambient operating temperature is 104
o
F (40
o
C).
Power
Be sure that the voltage and frequency is either 100-120 or 200-240
VAC and 60 or 50 Hz respectively. Since there is no external power
switch, power is applied when the power cord is connected.
Note
For countries other than the United States and Canada: use a
power cord that is rated at 6 amp, 250 VAC. Also note that this
cord cannot exceed 4.6 meters (15 ft.) in length and must be
made of HAR cordage with IEC fittings that are approved by
the country of end use.
