Operation 
 

For speech and announcements, the L50U is supplied with a hard-wired microphone handset, which clips 
onto the top of the housing for storage. Unclip the handset and hold the microphone (2) up to your 
mouth, press in the push-to-talk button (1) and speak. The volume is adjusted by an edge roller control 
(3) on the right-hand side of the handset. Sliding the push-to-talk button upwards when pushed in will 
latch it on, sliding it back down will unlatch the button. 
 
The side panel has controls for Whistle (4) and Siren (5) alerts. Pressing the Whistle button emits a loud 
alarm from the L50U, releasing this button stops the alarm. Pressing in the Siren button activates a loud 
siren alert, this button is latched and the siren will continue until the button is pressed again.  
 
Also on the side panel is a button for USB (6), which activates the rear-mounted USB/SD/AUX player. This 
button is also latched and the player functions are detailed below. 
 
A 6.3mm jack MIC input (8) is provided for an optional wired microphone. To use this, press in the 
latching MIC button (9). The level of the MIC input is governed by the microphone volume control (7) 
 
Note: The Whistle and Siren alerts will not sound properly if the USB or MIC buttons are pressed in.
