Getting Started

 

Take the Controller out of its pouch and open the sliding door on the left side. Insert 4 AA cells carefully 
observing the polarity as indicated on the side panel, the 2 cells in the outer slot facing both positive 
polarity outwards, the 2 cells in the inner tube positive polarity inwards. Then close the contact hinge 
and slide the door shut. 
The controller is designed to interface properly with other products of Ambient Recording's Lockit 
range. When connecting to 3

rd

 

party’s equipment carefully consult the referring user manuals for 

requirements to evaluate the possibility of proper interfacing. Follow the manufacturer´s instruction to 
the letter and only use the designed inputs with certified cables. Ambient cannot be held liable for any 
damage or malfunctions caused by improper set up and/or cabling. 

SWITCHING THE UNIT ON AND OFF 

A delay has been implemented to avoid inadvertent On/ Off switching. 

POWERING ON 

Press the 

ESC 

(On/ Off) key (red flash symbol) until the unit initializes displaying serial No. and software 

version. After a few seconds the display changes to default with the timecode generator screen 

(GEN)

POWERING OFF 

When switching off either standby or a complete power-down can be selected. In standby mode the 
timecode is held in the auxiliary TC generator (AUXGEN) that runs off the accurate internal reference 
while power-off helps to save battery life and is intended for long time no-operation. 
Press the 

ESC 

key. After a short delay the switch-off select menu will appear. 

 

  

 

 

Press ESC again: 

Unit is powered off for maximum save of battery capacity, timecode is lost. 

Press Enter: 

Unit enters standby mode, AUXGEN holds TC until batteries are drained completely.
