ELECTROMAGNETIC INTERFERENCE/
COMPATIBILITY

OTE: Nearly every electronic device is sus-

ceptible to electromagnetic interference
(EMI) if inadequately shielded, designed
or otherwise configured for electromag­netic compatibility.

Facilities

To avoid el ectromagnetic interference and/or
compatibili ty conflicts, turn off your device in any
f acility where posted notices instruct you to do so.
Hospit als or health car e facilities may be usin g
equipment that is sensiti ve to external RF energy.

Aircraft

When in st r ucted to d o so, turn off your device
when on board an aircraft. Any use of your device
must be in acc or dance w ith ap pl i cable regu la ­tions per airline crew instructions.

Medical Devices

Pacemakers

The Hea lth Industry Manufacture rs Association
recom m ends that a mi ni mum separatio n of 6
inches (15 centimeters) be maintained between a

4

wireless device and a pacemaker. These recom­mendati ons are consi st ent with the independe nt
resear ch by, an d re com mend at io ns of, Wireles s
Technology Resea rc h.

Persons with pacemakers should:

• ALWAYS keep the wireless device more

than 6 inches (15 cent i m et er s) from their
pacema ker when the device is tur ned ON.

• not carry the device in the br east pocket.

• use the ear opposite the pacemaker to min-

imize the pote nt ial for interference.

• turn the device OFF immediately if you
have any reason t o suspect th at inte rfer­ence is taki n g pl ace.

Hearing Aids

Some digi tal wir el es s radios may interfere with
some he aring aids. In th e event of such inter fer­ence, you may want to consult your hearing aid
manufacturer to disc uss alternat ives.

Other Medical Devices

If you use an y othe r personal me dical device,
consul t the m anufacturer of your device to deter­mine if it is adequately shiel ded from RF energy.
Your physician m ay be able to assi st you in
obtaining this information.

BLUETOOTH WIRELESS TECHNOLOGY OVERVIEW

At Motorola we believe that easy portable com­municatio n is the k ey to creating a safer envi ro n­ment. That’s why we designed this exciting new
two-way communicatio n device ca lle d th e R adio
Bluetooth Ada pt er (RBA). The RBA re pr esents
anothe r breakthrough in applyi ng Bl uetooth wire­less technology by Motorola. This adapter allows
your radi o to send and re ceive audio from a wi re­less accessory such as a Remote Speaker Micro­phone (RSM ) w ith out w ire s.

This RBA us es a new pro to col based on state-of­the-art Bluetooth techno lo gy specifications,
which re sult in simplifying th e use of your radio.
Bluetooth wireless tech nology is an open stan­dard, connecting wir el es s devices w ithin a short
range. The range for this particular adapter
(RBA ) and the Bluetooth audio accessory is
approximately 30 feet in ideal line-of-sight condi­tions. It is important to be aware that the specific
Bluetooth t echnology was designe d and engi­neer ed for use betwe en your radi o and special
Bluetooth audio acces sories. Yo ur Bluetooth
audio ac ces sor y w ill not operate with oth er non­Motorola two-way radio Bluetooth prod uc ts.

If your radio is VOX (voice activated transmission)
capable, the Bluetoot h wireless functionality will
continue w ith your adap t er a nd a VOX capa ble
Bluetooth wireless headset.

We’re confid ent that once you try the Bluetooth
wir eless adapt er and accessories, you’ll wonder
how you survived with all those attachment wires
in the first place!
