How do I turn on the megaphone?
Press and hold the Push-to-Talk (PTT) button while speaking into the built-in microphone. Release the button to stop amplification.
How do I activate the siren function?
Slide the mode switch from 'Voice' to 'Siren' or 'Alarm' position. Press the PTT button to trigger the siren sound. Slide back to 'Voice' for normal use.
How can I adjust the volume?
Use the volume dial on the side of the megaphone. Turn clockwise to increase volume, counterclockwise to decrease.
What is the maximum range of the MG-400?
The megaphone can project sound up to 400 meters (approximately 1/4 mile) in open areas, depending on environmental conditions.
How long do the batteries last?
Battery life is typically 20 hours with intermittent use. Actual duration varies based on volume level and frequency of use.
What should I do if there is no sound?
First, ensure batteries are installed correctly and have charge. Check if PTT button is pressed firmly. Verify volume dial is not set to minimum. If still no sound, replace batteries.
Can I use rechargeable batteries?
Yes, you can use rechargeable Ni-MH C batteries. Note that rechargeable batteries have lower voltage (1.2V vs 1.5V), so sound output may be slightly reduced.
