Inspect for damage
1. Inspect the shipping carton for evidence of physical damage or mishandling prior
to opening.
2. Inspect all parts for damage.
3. Report any damage to the carrier immediately.
4. If it is necessary to make a damage claim to the carrier, do not move the shipping
carton until it has been examined by a representative of the carrier.
Once the telephone is fully assembled, it is no longer necessary to keep the empty
cartons. Dispose of it in accord with local regulations.
Unpacking the Shipping Container
The following items should be present in the box containing the FlexSet telephone set:
1. Twisted Handset cord - connects the handset (receiver) to the telephone body.
2. Handset (receiver).
3. FlexSet telephone line cord - connects the phone outlet to the telephone body.
This is a four position modular jack. The two center conductors are the ones used;
polarity is not important.
4. The FlexSet comes with a preprinted label inserted beneath the faceplate.
Additional blank labels may be purchased from the dealer in Letter or A4 size
paper, as described on page 1-14.
5. FlexSet Quick Reference Guide (in some markets).

Peripheral Card Connections
For information on pin assignments for all I/O cable connections to the Coral
Peripheral Cards, refer to the relevant Coral installation manual for the corresponding
tables for the appropriate Coral Peripheral Card: (8/16/24)SFT, (8/16/24)SFT Office,
(4/8)SA8F Office, (4/8)SA16F Office, (4/8)S8F Office, (4/8)S16F Office, (8/16)SFTipx,
(8/16)SFTsl and 8F8Ssl.
In the following sections the 8SFTsl, 16SFTsl and 8F8Ssl cards are used in
Coral FlexiCom 200 and CDRS 200 systems, and 8SFTipx and 16SFTipx
are used in the Coral IPx 500 and CDRS 200E systems.
All other Peripheral cards can be installed in any Coral system, with the
exception of CDRS 200, CDRS 200E, Coral FlexiCom 200 and Coral IPx 500
systems. Standard Coral peripheral cards can be installed in CDRS 200 and
Coral FlexiCom 200 expansion cabinets only, not the main cabinet.
.
FlexSets cannot be used as power failure stations. See Power Failure Mode on page 2-9.
The FlexSet will be ruined by incoming ring voltage on a PF trunk.

Line Distances
FlexSet telephone sets are designed to operate over line distances (see below) using
internal power, supplied by the Coral station circuit. In order to extend the cable loop
limit, the FlexSet 280/281 series can be powered by an external power source located
at the station. Power adapters are explained in External Power Supply on page 8-1.
Maximum Line Lengths depend on the gauge wire used to connect the Coral to the
telephone keyset.
When using the internal power supply (supplied by the peripheral card), a simple rule
of thumb for any gauge wire is that the maximum DC resistance of the loop be
200 Ohms or less (175 Ohms for FlexSet 80 or GKT).
Maximum line lengths from (8/16/24)SFT, (8/16/24)SFT Office, (4/8)SA8F Office,
(4/8)SA16F Office, (8/16)SFTipx, (8/16)SFTsl and 8F8Ssl peripheral cards to the FlexSet
telephones are listed in Table 1-1.

To Connect the FlexSet to a Standard Wall Socket
1. Turn the telephone onto its back. There is a connector socket located on the lower
third of the telephone at the center, marked LINE (see Figure 1-3 and Figure 1-4).
Place either end of the telephone line cord into this socket. The cord comes with
the same connector type on both ends.
The connector will fit properly in one direction only. If the connector does not go
into the socket easily, turn the connector over and retry.

2. Thread the line cord through one of the grooves running along the underside of
the telephone, according to preference. This enables the rear panel to remain clean
and uncluttered. Turn the telephone right-side up.
3. Place the free end of the telephone line cord into the wall socket.
The connector will fit properly in one direction only. If the connector does not fit
into the socket easily, turn it over and retry.
After a brief pause the keyset will activate.
Handset and Twisted Cord
The handset cord comes with the same connector type on both ends.
1. Fully depress the cradle rubber pad and remove the protective tab. Discard the tab
in accordance with local regulations.
The purpose of the tab is to avoid continuous pressure on the cradle rubber pad in
the off-hook position during shipping and while packaged in boxes.

the Protective Tab
2. Turn the telephone onto its back. Take one end of the handset cord and place it
into the handset socket located on the underside of the telephone body. (The
socket is marked with a picture of a handset). See Figure 1-3 and Figure 1-4.
The connector will fit properly in one direction only. If the connector does not fit
into the socket easily, turn it over and retry.
3. Thread the handset cord through the groove running to the right of the handset
socket.
4. Place the free end of the cord into the socket located at the bottom of the handset.

If using a single unit power supply, insert the TPS (Telephone Power Supply) plug into
the jack marked “DC” on the rear of the FlexSet base (on those telephones equipped
with PEX or PEX/APA). The TPS is provided separately.
See External Power Supply on page 8-1 for more information.
Wall Mount or Desk Elevation Position
The FlexSet can be easily wall or desk mounted.
Refer to Wall Mount/Desk Elevation on page 3-1 for details.
