Feature button and terminal button is flashing

PUSH JUST THE BUTTON SPEAKER TWICE
IT MAKES THE HAND FREE CALL YOUR PHONE WAS FORGOTTEN ON FREE HANDS CALL

This is what I wrote up for our inhouse manual on telephone administration for this phone:

Problem: An employee pushes the Message button to receive a message but it calls someone else's desk. This is caused by whichever extension the phone forwards to when pushing the Message light. For example: if the person at 333 pushes their blinking message light and it forwards to 316 that means that the person at 316 most likely tried to call 333, got a busy signal and accidentally pushed the Message button before hanging up thus setting 333 to call forward to their extension when they got off the phone.

All phones on our system should have this feature turned off, but if it happens this is the two step process to resolve the issue:

Solution: First, push the Message button to figure out which extension it is forwarding to. Take note of the extension and hang up. With the hand set NOT picked up, dial #409 and Release. You may have to do this multiple times to clear the call forwarding because it needs to be done for each incidence that the person accidentally set up call forward. Finally, in the management software go to Station > Station Assignments. Select the extension # that the Message button was forwarding to (the one you noted above). Under the Basic tab at #41 Active Message Waiting select Disable. Select Submit.

You should be able to reestablish connection by pushing and briefly holding the connect button on the receiver until the light begins to flash. Once it's flashing you can push and briefly hold the connect button on the bottom of the mouse. Once they are synched the light on the receiver should turn solid.

Why are you pressing the feature button?

Press feature then answer. You envoked ringing line pick up.
Press feature then speed dial button, dial a number like your dialing out, then feature again. You've just set a speed dial button.
Press feature, then 3 and you've changed your ringtone on a series i phone.

Today I bought the Phillips SRU5107/27 Universal Remote Control and I was able to programmed my intec PS2 Remote Control. This control has the "learn" feature and you can program every single button and feature of your Intec.

Do not pick up the receiver press feature button dial 60 press feature button again, at least this worked for me.

Do NOT pick up the receiver - Push the "FEATURE" button - Dial 60 - Push the "FEATURE" button again - this worked for me. Good Luck!

replace the vacuum switc on the left side of the transfer case, should have 2 vacuum lines to it

You need to program the feature "recall" on a button.

On the phone you want to program, press Feature 00
press a button you can program as "Recall"
press feature 03
when finished, press feature 00 and you are done.

Recall is the "flash" button

Thankfully I have found a solution that has worked.

A 'winking' (flashing) feature button indicates the station is in call forward - all calls mode.

To cancel this setting do the following

Lift the handset or press speaker
Dial the access code 4 + 2 (set as default)
Receive confirmation tone and restore handset or press speaker

I have found the manual at the following link to be the best resrouce ever - very easy to understand
