7.5.4 Charging Batteries
• Install the battery with the battery contacts facing the charger. Slide the battery between the guide rails until it lightly latches in place.
The LED directly below the slot in which a battery is inserted lights up immediately.
A solid yellow LED indicates that the battery is being charged. If the battery temperature is outside 0˚ C to 39˚ C (32˚ F to 102˚ F), the LED flashes yellow until the temperature is acceptable. A fully discharged battery will normally take between 1.5 and 4 hours to charge. When the battery charge reaches 75%, the indicator flashes green. At full capacity, it turns solid green.
When the battery is fully charged, the charger stops applying power; the battery cannot be overcharged if left in the charger slot. The 75% charge indicator is handy if you need a quick recharge – it often occurs after less than an hour.
7.5.5 Troubleshooting
7.5.5.1
Excessive Charge Duration
The charger is equipped with a recalibration function – a function that fully discharges and then fully recharges the battery. This process is necessary to recalibrate the battery capacity gauge internal to the battery. The charger attempts recalibration when:
• the battery capacity is at less than 30%, and
• the battery has undergone more than 40 partial charge cycles since the last full discharge.
A complete battery discharge takes between 1.5 and 4 hours to complete. When in discharge mode, the LED indicator flashes yellow. The recalibration function extends the charge time by up to 2 hours.
7.5.5.2
Indicator Flashing Red
If the indicator flashes red:
• Remove all batteries and disconnect the mains power cable.
• Wait at least 20 seconds, and then plug the cable in again.
If any of the charge slot LEDs continue to flash red, the charger is defective and requires service. If all indicators are flashing red, there is a power supply problem and the charger requires service.

7.7.4 Troubleshooting
Troubleshooting issues for the combo dock are identical to those of the quad dock.
Refer to “Troubleshooting” on page 219 for helpful tips.
7.8 Quad Dock
The Quad Dock permits each of four docked 7535 hand-helds to communicate with a 10/100 BaseT Ethernet network at greater than 2Mbps. It also provides sufficient power to operate and fast charge the batteries the 7535s.
7.8.1 Installation
The quad dock should be located away from excessive dirt, dust and contaminants.
The ambient temperature must fall between 0˚ C to 39 ˚C (32˚ F to 102˚ F). The
7535 internal charger will not charge batteries outside of this temperature range. For maximum performance, it is recommended that the quad dock be operated at room temperature – from 18˚ C to 25˚ C (64˚ F to 77˚ F).
The quad dock can consume up to 3A @ 120VAC or 1.5A @ 240VAC. Ensure that the mains circuit supplying the unit is adequate, especially if several docks are being powered from the same circuit.
After unpacking the unit:
• Visually inspect the unit for any damage.
• Install the IEC power cord and apply power.
A green indicator in the lower-right corner of the front panel lights up to indicate that power is present.
• Attach a CAT5 RJ45 network patch cable (supplied) between your network and the RJ45 jack on the rear of the dock.
A green LED is illuminated next to the RJ45 connector when a valid network link is established.
A user application must be loaded onto each 7535 that utilizes the quad dock for communication. When the network is connected and this application is loaded, the quad dock is ready for use.

Indicators And Controls
7.8.2 Indicators And Controls
The quad dock has no user controls. It is equipped with a power indicator LED and
RJ45 link and traffic indicator LEDs. When a valid network link is established, a green LED is illuminated next to the RJ45 connector.
7.8.3 Using The Quad Dock
• Gently slide the 7535 into the cradle portion of the quad dock until lightly latched.
The 7535 detects that it is in a quad dock and displays the appropriate icon in the taskbar – . The battery charge LED on the 7535 lights up to show it has external power and may start charging the battery.
Interaction with the 7535 while in the quad dock is a function of the user application software used to communicate with the host network.
7.8.4 Network Access
The quad dock includes a four port 10/100 Ethernet hub. Each of the four downstream ports are connected to dedicated USB-to-Ethernet converters. These
USB converters appear as USB slaves to the 7535 USB host controller. The 7535 automatically detects insertion into a quad dock and loads the appropriate drivers to communicate with the USB/Ethernet converters.
7.8.4.1
Network Addressing
Although the USB converters have fixed Ethernet MAC addresses, there is generally no correlation between these addresses and a specific 7535 hand-held. The host application uses a standard TCP/IP protocol to name, locate and communicate with a 7535 on the network.
If a link is established between a 7535 and a host, the application on the host and on the 7535 must have a recovery mechanism in the event that the 7535 is removed from the dock and the link is interrupted.
