Introduction
Thank you for purchasing the Skutch
CK-1A4 Promotion-On-Hold Module for
the AT&T 1040, 1070, and 1080 four line
phone system. This unit ONLY works
with these 3 phone models. The CK-1A4
is a true plug and play device. This unit
requires an external sound source such as
a Digital MP3 Player to provide the
Promotion-On-Hold audio. When a call is
placed ON HOLD from any of the
phones, the ON HOLD caller will hear the
Promotion-On-Hold audio. When the line
is re-answered, the audio automatically
stops. It's that simple!

Installation
The SENSOR Board MUST be stuck to
the phone or this unit will not function.
The Sensor Board has a plastic PAD that
has been custom made to fit the contour of
the telephone. This makes it very easy to
align the sensor board. The Sensor Board
should almost snap in to place and fit
snuggly. We have supplied extra adhesive
strips in case they are needed.

CK-1A4 Installed on 1040

1- Position the CK-1A4 box under the telephone with the jacks facing towards the back
of the phone. (See Fig. 3).
2- Make sure that the surface on the telephone is clean and free of dust and/or oil.
3- Peel the two paper protectors off back side of the "SENSOR BOARD" . Align the
SENSOR Board as shown in Fig. 2. Note that the SENSOR Board will almost click into
place because it has been designed to fit the contour on the phone. Make sure that the
SENSOR Board fits flush against the phone, and press down on it to secure it. The
SENSOR Board should be completely covering the Line lights on the phone.

Testing the System:
1- Pickup line 1 on your telephone. The line one GREEN LED on the SENSOR BOARD
should light up.
2- Repeat this test for lines 2-4. If all lines light up when picked up, the CK-1 is working
properly. If the lights on the SENSOR BOARD do not light up, then
a) Make sure that the CK-1 and Phone is connected to power.
b) Make sure that the SENSOR BOARD is aligned as shown in(Fig 2.

I hear Music when I pick up the phone
It is normal to hear a burst of music when a call is picked up from a HOLD condition.
The maximum length of the burst should be under 1 second. This is normal and is due to
the communication structure of this family of phones.
Lights on CK-1 Box.
When you place a line on HOLD, the corresponding LED on the rear of the CK-1A4 box
lights up to confirm the Promotion-On-Hold condition. During testing, make sure that the
GREEN light on the SENSOR Board is on steady for 3 seconds before placing the line
ON HOLD.
Using Other Phones with the 1040, 1070, and 1080
Phones
These AT&T phones are "Non-Friendly" to foreign phones and should NOT be used
with any other model of phone, including other AT&T models. If you place a 1040 on
hold, the hold condition can not be cleared by any other model of phone. The CK-1A4
will ONLY provide Promotion-On-Hold audio when a call is placed ON HOLD from
ONLY the AT&T 1040, 1070, or 1080 phones.
