The CK7 "Hold Button" Adapter was designed to provide
a Music/Message On Hold audio input "Specifically"
for the RCA 25403, RCA 25404, RCA 25413, RCA 25414 and RCA 25415...
or the GE 25403, GE 25404, GE 25413, GE 25414 and GE 25415..
or the PP 25415 Executive telephones, and now also the RCA/GE
25423, 25424 & 25425 series. This Music/Message On Hold
adapter unit connects to any one of your telephones and provides
Music-On-Hold capibility for all of your compatible phones.
With the CK-7, you now have an audio input to provide you with
seamless "HOLD" button activated message/music on
hold when used with your favorite player or audio source. It
doesn't matter how many phones you have, one CK-7 Music On Hold
unit will work with all of them.
(NOTE: The CK-7 WILL NOT work with the 2 line RCA/GE 25202 (RE3)
model phone. The 25202 needs the Skutch
BA-704-2 STAR TONE on hold adapter!)
This "wall mounted" unit works automatically in the
background every time you press the HOLD button on any of your
corded/cordless models listed above. This unit lets your message
sound its best "On-Hold" from Cassette Players, CD
Players, PP Players, PC Sound Card Output, or any Powers Productions
Digital Player (including our Pre-owned models. NOTE:
An expernal audio player is required to feed Message On Hold
audio into the CK-7. Please call us for ideas and pricing.)...
The CK-7 Music/Message On Hold unit is much better than most
any other telephone Music On Hold adapter currently on the market,
short of buying an expensive telephone KEY system (PBX/KSU).
