Safety Guidelines
The general safety information in this guideline applies to both operating and service personnel. Specific warnings and
cautions will be found in other parts of this manual where they apply, but may not appear in this summary. Failure to comply
with these precautions or specific warnings elsewhere in the manual violates safety standards of design, manufacture, and
intended use of equipment. Westell Technologies assumes no liability for the customer’s failure to comply with these
requirements:
Grounding: This digital repeater system is designed to operate from 100 - 240 VAC and should always be operated with
the ground wire properly connected. Do not remove or otherwise alter the grounding lug on the power cord.
Explosive atmospheres: To avoid explosion or fire, do not operate this product in the presence of flammable gases or
fumes.
Lightning danger: Do not install or make adjustments to this unit during an electrical storm. Use of a suitable
lightning arrester, such as Westell Technologies CSI-CAP, is strongly recommended.
No user serviceable parts inside. Hazardous voltages are present when the cover is removed. Opening the chassis will
void your warranty. If you suspect a malfunction with this product, call your dealer or Westell Technologies technical
support line at 1.877.844.4274
CAUTION!
Power off before connecting/disconnecting cables.
Important Safety Information
Antennas used for the purpose of radiating signals indoors are limited to a maximum gain of 3 dBi. The outdoor antenna
used for the purpose of communicating to the wireless infrastructure is limited to 14 dBi gain, or any combination of gain
and loss that equates to 14 dB at input. Each antenna must be positioned to observe minimum separation requirements
from all users and bystanders. The following guidelines should be used when considering separation distances.

Indoor antennas must be placed such that, under normal conditions, personnel cannot come within 20 cm (~8 in) from
any inside antenna. Adhering to this minimum separation will ensure that the employee or bystander cannot exceed
RF exposures beyond the maximum permissible limit as defined by section 1.1310 i.e. limits for general population/
uncontrolled exposure.
Outdoor antenna must be positioned such that, under normal conditions, personnel cannot approach closer than 183 cm
(~6 ft). A directional antenna having a maximum gain of 14 dBi is used, precautions should be taken to prevent personnel
from routinely passing through the main radiation beam at a distance closer than specified.
Radio and Television Interference
This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of
the Federal Communications Commissions (FCC) rules. These limits are designed to provide reasonable protection against
harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses
and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may
cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause
harmful interference in which case the user will be required to correct the interference at his own expense. In order to
maintain compliance with FCC regulations shielded cables must be used with this equipment. Operation with non-approved
equipment or unshieled cabled is likely to result in interference to radio and television reception. Changes and modifications
not expressly approved by Westell Technologies can void your authority to operate this equipment under FCC rules.
