(1) Lift the hold key (left line switch plunger)
and turn the line key to pick up the second
line.
(2) When the call on the second line is completed,
turn the line key back to the first line
position and then depress the hold key.
Note: Failure to depress the hold key will
automatically place a hold on the unused line
preventing its being used for either incoming
or outgoing calls. Reversal of this procedure
(i.e. depressing the hold key before switching
the line key back to the first line position)
will disconnect the first line.
(3) If the second line is to be picked up by an
extension station, the hold key is left operated
(lifted) until the extension is answered. After
the extension handset is lifted, the hold key
(first set) must be depressed to permit conversation
path of the extension.
(4) The hold key is automatically returned to
normal when the handset is replaced.

4. MAINTENANCE
4.01 Maintenance of the 2700-type telephone sets
is limited to replacing defective components.
4.02 Housings, handsets, and cords may be cleaned
with a damp KS-2423 (or equivalent) cloth.
Do not use scouring cleaners or volatile
solvents as these
may
damage finish.
4.03 Refer to sections covering dials, handsets,
cords, ringers, etc., for maintenance of these
components.
4.04 Those housings manufactured from 1970
through 1974 must be modified due to a
clearance problem, if they are used with a base
containing a P-type ringer and/or 4228G network.
Modify as follows.
(1) Using diagonal side cutters, clip off a portion
of the plunger-well snap-tabs, which
interfere with the P-type ringer and/or network,
as shown in Fig. 10.
Note: Tabs should be cut at an angle leaving
1/16-inch at the plunger well. Tabs longer
than 1/16-inch will cause the plunger to bind
when housing is installed. Tabs less than
1/16-inch will permit plunger to fall through.
