OPERATING MANUAL 2945A<br />
Do not charge at an ambient temperature of greater than 40°C.<br />
Do not dispose of in a fire. Do not short circuit. Do not crush, puncture, open, dismantle or<br />
otherwise mechanically interfere with. Do not store at temperatures in excess of 60°C.<br />
Do observe the correct polarity and connect correctly.<br />
During normal service, small quantities of hydrogen and oxygen may be vented from the battery<br />
pack. Adequate ventilation must be provided around the instrument to allow these gases to<br />
disperse naturally.<br />
The battery pack must only be charged using the charging facility in the instrument, or by using an<br />
approved sealed lead-acid battery charger.<br />
The normal ’End of Life’ condition is reached when capacity of the battery pack falls to 50% of its<br />
rated capacity. This is shown in the per<strong>for</strong>mance specification in Chapter 1 of this manual. Battery<br />
packs should be withdrawn from service when this condition is reached.<br />
Battery storage<br />
Any sealed lead-acid battery naturally self-discharges when in storage. Its service life and capacity<br />
may be adversely affected if it becomes over-discharged. Refer to the per<strong>for</strong>mance specification in<br />
Chapter 1 of this manual <strong>for</strong> storage time and conditions.<br />
Stored battery packs should be periodically ’Top Charged’ to optimize per<strong>for</strong>mance and service life.<br />
Be<strong>for</strong>e ’Top Charging’, the open circuit voltage must be measured, and if this is below the<br />
minimum shown in the per<strong>for</strong>mance specification in chapter 1 of this manual, the battery pack must<br />
not be recharged.<br />
Hot Surfaces<br />
Take care when touching the RF Input Type N connector after the application of high levels of<br />
continuous power. If 50 W is exceeded <strong>for</strong> a prolonged period, the temperature of the connector<br />
can become excessive.<br />
RF hazard<br />
When measuring high VSWR ratios, hazardous voltages may be present on the line due to standing<br />
waves. Under these conditions, it is dangerous to operate the equipment with the covers removed.<br />
Tilt facility<br />
When the equipment is in the tilt position, it is advisable, <strong>for</strong> stability reasons, not to stack other<br />
equipment on top of it.<br />
