Humminbird 1155C - Manual (Page 103)

Alarm Volume
Alarm Volume allows you to adjust the volume of the alarms.
To change the Alarm Volume setting:
1. Highlight Alarm Volume on the Alarms main menu.
2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Alarm Volume setting. (Off, 1 -
10, Default = 5)
Low Battery Alarm
Low Battery Alarm sounds when the input battery voltage is equal to
or less than the menu setting. The battery alarm will only sound for the battery that is connected to the
1100 Series™. The Low Battery Alarm should be set to warn you when the battery voltage drops below the
safety margin that you have determined. For instance, if you are running a trolling motor (battery
operated), you would want to set the Low Battery Alarm to sound before the battery voltage drops too low
for it to be used to start your main, gasoline-powered engine.
NOTE: Your unit will detect when your battery voltage is too low or too high, and will display either Input Voltage
Low or Input Voltage High messages if these limits are exceeded. If you turn the Low Battery Alarm on using the
Alarms Main Menu, your unit will use your settings. If you do not turn the Low Battery Alarm on, the unit will
use these limits: 7.5 to 7.9 VDC for the low end, and 21 to 21.2 VDC for the high end.
To change the Low Battery Alarm setting:
1. Highlight Low Battery Alarm on the Alarms main menu.
2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Low Battery Alarm setting. (Off,
8.5V - 13.5V, Default = Off)
Temp. Alarm
Temp. Alarm sounds when the water temperature detected by the
1100 Series™ reaches the Temp. Alarm setting, which is either set in degrees Fahrenheit or Celsius
[International models only]. For example, if the Temp. Alarm is set to 58° Fahrenheit, and the water
temperature falls from 60° to 58°, the Temp. Alarm will sound. Similarly, if the water temperature rises
from 56° to 58°, the Temp. Alarm will also sound.
To change the Temp. Alarm setting:
1. Highlight Temp. Alarm on the Alarms main menu.
2. Use the LEFT or RIGHT 4-Way Cursor Control keys to change the Temp. Alarm setting. (Off, 32-120
[Fahrenheit], 0-50 [Celsius (International models only)], Default = Off)
