How can I obtain a telephone modem back-up battery?

Currently, WAVE will provide an internal 8-HOUR back-up battery for WAVE-supplied telephone modems at no charge, upon request from the customer [and will replace the 8-HOUR back-up battery without charge, upon request, as needed].    Batteries may be obtained at the time your telephone modem is installed or by calling 866.928.3123.  This policy may be subject to change at a future date, in which case you will be notified.
