VK3YNG Sniffer 4 Instruction Manual (for V2.2 hardware)

Auto Power Down

The sniffer will automatically power down if either of the following two conditions

are met:

1) There has been no key pressed for at least 10 minutes.

2) There has been no "upward" progression in range for at least 10 minutes.

The sniffer will give five short beeps just before the unit powers down.

The sniffer functions accurately to supply voltages down to approximately 2.7 volts.

Below this the accuracy becomes compromised or the sniffer may power itself down.

When power has dropped to 2.7 volts or lower, the display decimal point is enabled to

warn the user that batteries are in need of replacement.

A high efficiency Seven Segment Red LED is used for the range display. It has two

brightness settings, one for daytime use and a significantly reduced brightness level

for night use. A light sensor located immediately above the display automatically

determines the brightness level.

This mode may be useful for children or first time operators. It allows the sniffer to be

used in its most basic format and hides all programmability options from the user.

This mode is very useful for scout foxhunting for example. For this reason, many

refer to this mode as "Scout Mode".
