Caution

  • Before normal flash photography, select WIRELESS OFF to clear the wireless (sender/receiver) settings.

Setting the Transmission Channel / Wireless Radio ID

Set the sender's transmission channel and wireless radio ID as follows. Set the same channel and ID for both the sender and receivers. For receiver instructions, refer to the instruction manual of Speedlites equipped with radio transmission wireless receiver functionality.

Caution

  • Set different wireless radio IDs for each channel, because interference between systems with Speedlites controlled by radio transmission may occur even if the units are set to different transmission channels.

  1. Push the joystick straight in.

  2. Select item (1).

    • Press the joystick vertically or horizontally or turn Select dial to select the channel item, then push the joystick straight in.

  3. Set a transmission channel.

    • Press the joystick vertically or horizontally or turn Select dial to choose from AUTO or channels 1–15, then push the joystick straight in.

  4. Select item (2).

    • Select the ID item just as you set the transmission channel, then push the joystick straight in.

  5. Set the wireless radio ID.

    • Press the joystick horizontally or turn Select dial to select the position (digit) to set, then push the joystick straight in.
    • Press the joystick vertically or turn Select dial to select a number in the range 0–9, then push the joystick straight in.
    • Set a 4-digit number the same way, then select OK.
    • The LINK lamp is lit in green when communication is established between the sender and receiver.

Scanning and setting sender transmission channels

You can scan radio signal conditions and then set the sender transmission channel automatically or manually. Setting the channel to [AUTO] will automatically reset the Speedlite to the channel with the strongest signal. When setting the channel manually, you can review scan results as you reset it.

  • Scanning when currently set to [AUTO]

    1. Press the SUB MENU button.

    2. Run the scan.

      • Press the joystick vertically or horizontally or turn Select dial to select SCAN, then push the joystick straight in.
      • Select OK.
      • The scan is performed, and the setting is reset to the channel with the strongest signal.

  • Scanning when currently set to a channel (1–15)

    1. Press the SUB MENU button.

    2. Run the scan.

      • Press the joystick vertically or horizontally or turn Select dial to select SCAN, then push the joystick straight in.
      • Select OK.
      • The scan is performed, and a graph of signal conditions is displayed.

      • Higher peeks in the graph indicate stronger signals.

    3. Set the channel.

      • Press the joystick horizontally or turn Select dial to choose a channel in the range of 1–15.

      • Push the joystick straight in to set the channel.

LINK Lamp and Connection Indicator

You can determine the connection status from the state of the LINK lamp or the icon on the LCD panel.

Status Description Action
Lit Connected –
Off Not connected Check the channel and ID
Off Too many units Do not exceed 16 senders and receivers, combined
Off Error Restart the senders and receivers
Lit Connected*1 –
Lit Connected*2 –

1: When the sender side is connected to the sub-sender

2: When the sender side is connected for linked shooting

Display Description Action
Sender wireless connection / Receiver wireless connection Connected –
Sender wireless not connected / Receiver wireless not connected Not connected Check the channel and ID
Sender unit wireless error / Receiver unit wireless error Too many units Do not exceed 16 senders and receivers, combined
Error Restart the senders and receivers
SUB SENDER Connected*1 –

1: When the sender side is connected to the sub-sender

Caution

  • Receivers do not fire unless the sender and receiver channels match. Set both to the same number, or set both to [AUTO].
  • Receivers do not fire unless the sender and receiver wireless radio IDs match. Set to the same number.

Sender Flash Firing On / Off

You can set whether the sender fires along with the receivers it controls wirelessly. When sender flash firing is enabled, the sender fires as firing group A.

  1. Push the joystick straight in.

  2. Select the item shown in (1).

    • Press the joystick vertically or horizontally or turn Select dial to select the item, then push the joystick straight in.

  3. Set sender flash firing.

    • Press the joystick horizontally or turn Select dial to enable or disable sender flash firing, then push the joystick straight in.
      • Sender flash firing ON: Sender flash firing ON
      • Sender flash firing OFF: Sender flash firing OFF

Note

  • Disabling sender flash firing expands the available flash output range from 1/1024 to 1/8192.

Modeling Lamp Wireless On / Off

The modeling lamp of connected sender/receiver units turns on and off in response to pressing the sender LAMP button when the EL-5 is a sender or receiver. This way, you can check subject shadows created by multiple Speedlites simply by operating the sender. Pressing the sender camera shutter button completely also turns off the modeling lamp of receivers.

Caution

  • When sender flash firing is disabled, the LAMP button does not activate the sender modeling lamp.
  • Modeling lamps of firing groups set to OFF flash mode and other non-firing groups are not activated.
  • Any changes to flash modes or firing groups while a modeling lamp is on do not alter the current illumination status of the lamp. Before changing these settings, turn off the sender modeling lamp as needed.

Note

  • Receiver modeling lamps can be turned on or off even by a sub-sender.
  • Brightness and duration of modeling lamp illumination depends on the settings of each receiver.
  • As an indicator of modeling lamp illumination commands, Modeling lamp indicator (1) on firing group control information does not necessarily correspond to the current status of receiver modeling lamps.
