The same as the regular CradleMate with the addition of an illuminated message box to indicate you're on line. The light box has a long cord so you can place the message where visitors will see it first. This is a MUST for the busy office! Two adjustable mounting plates configure the CradleMate for any phone. Attaches securely with self-adhesive Velcro(TM) patches. Light box requires 2 "AA" alkaline batteries (included).
