For transmitters rated at a maximum output power not listed above, the recommended separation dis-
tance d in metres (m) can be estimated using the equation applicable to the frequency of the transmitter,
where P is the maximum output power rating of the transmitter in watts (W) according to the transmitter
manufacturer.
NOTE 1 At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects and people.

where P is the maximum output power rating of the transmitter
in watts (W) according to the transmitter manufacturer and d is
the recommended separation distance in metres (m).

Field strengths from fixed RF transmitters, as determined by an
electromagnetic site survey, a should be less than the compli-
ance level in each frequency range.b
Interference may occur in the vicinity of equipment marked

with the following symbol:

NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorp-
tion and reflection from structures, objects and people.

a Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and
land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted
theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an
electromagnetic site survey should be considered. If the measured field strength in the location in which the
device is used exceeds the applicable RF compliance level above, the device should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be necessary, such as
reorienting or relocating the device.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 10 V/m.

Note: If the unit still does not work, contact HoMedics Consumer

Relations. Under no circumstance should you disassemble or
attempt to repair the unit by yourself. Contact information for
HoMedics Consumer Relations Department can be found on

CAUSES

CORRECTION

Unit does not
turn on when the
START/STOP
button is pushed.

Batteries have
run down.

Replace them
with two new “AAA”
alkaline batteries.

Battery polarities
have been positioned
incorrectly.

Re-insert the
batteries in the
correct positions.
