PRODUCT COMPATIBILITY

While every effort has been made to verify operation of this product with many different communications

products and networks, Cylink Corporation makes no claim of compatibility between its products and other

vendors’ equipment. It is assumed that users have thoroughly evaluated this product’s performance in the

communications environment in which it will be used.

SAFETY

The following general safety precautions must be observed during all phases of operation and service of this

product. Failure to comply with these precautions or with specific warnings elsewhere in this Manual willfully

violates standards of design, manufacture, and intended use of the product. Cylink Corporation assumes no

liability for the customer's failure to comply with these requirements.

This product must be grounded. In the event of a short circuit, grounding reduces the risk of electrical shock

by providing an escape wire for the current.

The product's AC power cord ends in a three-pole grounding plug. Do not use a three-pole to two-pole

adapter with the plug. Verify that the outlet you intend to use is properly installed and grounded; the outlet

used must comply with the local electric code.

Do not install or operate this product in the presence of flammable gases or fumes. Operation of any

electrical instrument in such an environment constitutes a definite safety hazard.

No user maintained or adjustable components are present within this product. The covers should not be

removed by anyone other than authorized Cylink service personnel. The potential for electrical shock exists

within the cabinet at all times unless it is unplugged.

Do not install substitute parts or perform any unauthorized modification to the VoiceXtender modems.

Return the product to Cylink Corporation for service and repair to ensure that safety features are

maintained. Prior to returning any product(s) for repair, contact Cylink at the telephone numbers or address

located on the front of this Manual, and obtain a Return Material Authorization (RMA) number.

Changes or modifications not expressly approved by Cylink Corporation can void the user’s authority to

operate the equipment.
