Figure 3: Removing the Battery Cover
NOTE: When replacing batteries, use 6 C cells that are the
same type. Do not mix half used alkalines with brand new
ones.
CAUTION: Remove batteries entirely before shipping.
Operation Time
Typical operation time varies for the ST-305, depending on
factors such as load, environment, and current transmitted.
Other factors that affect the operation time will include
chemistry of the battery (many of the new high performance
batteries, such as the “Duracell ® ULTRA” last 10%-20%
longer than conventional alkaline cells under high demand
applications). Operation at low temperatures will also reduce
battery life.
Batteries often recover after being subjected to high loads.
If time is allowed, batteries may recover enough to offer
additional hours of operation.
Powering Up / Down
Turn the power ON by depressing the Power Key on the
keypad. The current frequency and power level LEDs will
light up. A beep will sound.
Turn the unit OFF by depressing the Power Key on the
keypad for 2 seconds. Three tones will sound.
Automatic Shut Down
To save energy, the ST-305 will automatically shutdown after
an interval which varies with the power setting:
Low Power 4 hours
Medium Power 2 hours
High Power 1 hour
Battery Check
At start-up, the ST-305 will check available power and will
indicate estimated battery levels by lighting one, two, or
three LEDs in the right hand column (power level) on the
control panel. These levels are only estimates based on a
rapid internal check. A rapid series of beeps will sound if the
battery levels run low in operation.
Sounds of the ST-305 Transmitter
Sounds are associated with specific events or states.
They include:
• Beeps – Beeps when current is flowing; rate increases
with current increase.
• Beeps – Turn ON (4 beeps)/OFF (3 beeps).
• Short Double Tone – Inductive Clamp connected.
• Long-Short-Short Tone – Inductive Mode.
• Rapid series of beeps – Low Battery Warning.
The sound may be toggled on or off by pressing the Frequency
and Power buttons simultaneously.
