=== Exercise ===
'''Private Ringing indication'''
*When calling the Main Guard in private ringing mode, a lamp controlled by the relay in the station should be activated when the private ringing starts. (The Main Guard must be set in “Private” mode by pressing the C-key for more than 2 sec.).
*The lamp should be turned off when the private ringing stops.
* Use logical RCO 10 to operate the relay


'''Call Queue indication'''
*When the Main Guard receives a '''Call Request''', the same lamp should be activated to indicate that there is one or more calls in the call queue (Tip: Use event "Priority Mail Present").
*The lamp should be turned off when there are no more calls in the queue.
